The flanges may be flat or raised face. They should be without burrs, weld spatters or sharp edges and free from oil. (EPDM is not oil resistant). 1) Flange gaskets are not necessary since the rubber lining extends onto the faces and therefore acts as a gasket. During installation of the butterfly valve the direction of flow is irrelevant because the valves provide 100% bi-directional tight shut off. Important For flared flanges to DIN 2642 Reihe 1/Table 2, carefully centre the shut-off valve using a gasket. With plastic flanges it is advisable to use flat flanges or to fill up the space be- tween the short double flanged valve and the raised face. It is advisable to mount butterfly valves having bores larger than 300 mm with the valve shaft positioned horizontally for the following reasons: - self-cleaning action is ensured; consequently no settling nor any deposits on the lining (see sketch 1). - the weight of the valve disc is evenly distributed over the bearings. - by centring the valve disc no dis proportionate pressure can be exerted on the lining. 2) Note: If it is only possible to install vertically, consult AVK. Centring during installation Wafer type: 3) - For wafer types smaller than 350 mm centre by means of bolts placed around the butterfly valve body. - From 350 to 600 mm 4 centring holes are provided. - For bores above 600 mm drilled or tapped holes are provided. For the other types, centre by means of the bolt holes in the integrally cast flanges of the valve body. For further specification, see section "Technical information". The designs, materials and specifications shown are subject to change without notice due to our continuing programme of product development. AVK INTERNATIONAL A/S/99

176 AVK BUTTERFLY VALVES 75 Mounting and operating instructions for butterfly valves General aspects in installation - The pipings must be perfectly aligned with their flanges parallel to avoid deformation and material stresses in the valve and the bolts. - Concentric installation in the pipeline. - The bore of the connecting flange must not be smaller than the bore of the butterfly valve, the disc must be able to turn freely in the pipe (see sketch 2). - If the bore of the connecting flange is large it must have sufficient sealing surface in contact with the rubber lining to obtain perfect sealing. - The flange bolts must be tightened in a diagonal sequence, until the butterfly valve body touches the flange and an even all round contact is obtained (see sketch 3). - Clean and pressure test the piping before start-up with the valve in the open position. (max. test pressure: 1.5 x PN). Ensure that cleaning chemicals are compatible with the valve materials. - Avoid heating the rubber lining. Do not weld a flange to a pipe with the butterfly valve installed. Storage - Store in dry, dark, and cool conditions. - Open the valve disc approx. 10. Maintenance Routine maintenance is not necessary under normal conditions. Periodically re-tighten the (flange) bolts after a long operating time. Spare parts The AVK butterfly valve is designed for a long maintenance free service life, and if the right materials are chosen, no spare parts are needed. If abrasive media are used or in case of accidents, a rubber-lined body and a valve disc can be delivered as spare parts for sizes up to 300 mm. For larger dimensions the whole valve must be replaced. Note: For aggressive media and where abrasive wear occurs, the flow rate in the piping should be as low as possible. Avoid mounting the butterfly valve in or near bends. Lining wear almost certainly means disc wear and repair is rarely an economic option. Retrofitting or replacement of actuators such as wormgears, pneumatic, hydraulic or electric actuators If a drive must be installed on the free shaft of the butterfly valve, the following points are important: - The drive must fit smoothly onto the square of the butterfly valve, a forced assembly causes leakage at the upper shaft and increased rubber wear on the lower shaft. - When aligning the drive (using the set bolts for example), the valve disc must be replaced exactly on the body centreline. This can be controlled with a depth gauge. - The clearance of the valve shaft and the shaft of the drive shall not exceed 0.1 mm.

177 AVK BUTTERFLY VALVES 75 Material options Material selection for butterfly valves, metals and elastomers: The choice of materials for butterfly valves depends on many factors. The most important are the following, which are to be stated on inquiry: - Working pressure / pressure class / test pressure - Medium - Temperature - Requirements with regard to corrosion and erosion resistance The correct choice of the rubber is dependant on the duty, i.e. the medium and its temperature. NBR / NBR-DVGW Has good resistance to aliphatic hydrocarbons, animal oils and fat, water and watery media. NBR is excellent for gas applications. Its resistance to ozone and weather influences is however moderate and NBR is not resistant to aromatic and chlorine hydrocarbons. NBR has good mechanical as well as elastic properties and can, depending on the medium, be used within the temperature range of 0 C up to 90 C. EPDM Is extremely resistant to ozone, weather influences and chemicals such as acids, ketones and alcohol. EPDM is not resistant to aliphatic, aromatic and chloride hydrocarbons. EPDM has good mechanical as well as elastic properties and can, dependant on the medium be used within the temperature range of -40 C up to +120 C. FPM (Viton, available in B50 and GF quality) Has excellent resistance to aliphatic, aromatic and halogen hydrocarbons as well as oxydating acids. Also good resistance to ozone and weather influences. FPM has reasonable mechanical and elastic properties and can, depending on the medium, be used from 0 C up to 200 C, however standard FPM should not be used with hot water. Vulcanizing AVK butterfly valves are vulcanized using the "transfer injection moulding method" Inspection, via quality assurance, include the following points: - "peel off" test - homogenity (via ultrasonic test) - compression (amount of elasticity after impression) - hardness (shore) Material combinations The standard material combination is stated in the data sheets.

The dynamic torque acts in the closing direction and reaches a maximum at about degrees open. Td = Ct x D 3 x p D = Disc diameter (mm) P = Pressure drop across the valve The maximum value of Ct, at 75 open is Provided the liquid flow velocity does not exceed 4 m/sec., this torque Td needs not be considered for rubberlined valves. Hydrostatic torque (Th) This is the torque, caused by the difference in static head of liquid on the valve disc above and below the valve-shaft, when the valve is in a horizontal pipeline with the shaft also horizontal. Th = 4.81 x 10-7 x D 4 This torque becomes of practical importance only for valves larger than DN 1000.

240 AVK GATE VALVES 55/30 Installation and Maintenance Instructions 1. Introduction AVK series 55 gate valves are available in DN 450, 500 and 600. The valve has a full and straight bore corresponding to the nominal diameter and can be installed independent of the flow direction. To keep the advantage of the full and straight bore vertical installation is recommended, however, flow/pressure limitations outlined below should be observed. The valves are 100% factory tested hydrostatically to DIN 3230 part 4, PN 10 and PN 16. The valves are suitable for installations with flow velocity up to 5 m/sec. with max. 16 bar differential pressure across the closed valve. The valves have a standard gland flange according to ISO Various optional extras can be supplied factory fitted or in kit form for retrofitting. See data sheet. A complete By-Pass system is factory fitted. The By-Pass system secures an optimum installation due to slow filling and emptying of the pipe line and passing of air. AVK series 55 gate valves have many applications. IT IS THEREFORE IMPORTANT TO STATE OPERATING TEMPERATURE, PRESSURE, MEDIUM AND OPERATING CONDITIONS WITH ENQUIRIES/ORDERS, SO THE MOST SUITABLE VALVE WILL BE SUPPLIED FOR YOUR SPECIFIC PURPOSE. 2. Installation 2.1. Gasket To ensure adequate sealing it is important to select the correct type of gasket for the medium concerned. 2 gaskets with the correct flange size must be used Bolts Bolt size The following table shows which bolt diameter you should use for which valve dimensions.

Tighten all nuts as shown on the drawing in section Tighten all nuts with 100 Nm. The By-Pass system is now ready for use.

242 AVK GATE VALVES 55/30 Installation and Maintenance Instructions 3. Operation 3.1. Right-hand closing valves Closing During manual operation the valve is closed by turning the handwheel clockwise until the valve is completely closed, however only up to max. operating torque (see table 3). For valves supplied with gears, the handwheels are also turned clockwise. It is IMPORTANT that the interchange of the gear is taken into consideration, so that the valve is not operated at a higher torque than the max. operating torque (see table 3). When closing valves with actuators, adjust the actuator so that the output shaft moves clockwise, and adjust the on/off torque switch so that the valve is not operated at a higher torque than the max. operating torque (see table 3) Opening The valves are opened by turning the handwheel, gear or actuator anti-clockwise until the valve is completely open. This is recognized by a powerful (and sudden) stop Left-hand closing valves Closing During manual operation the valve is closed by turning the handwheel anti-clockwise until the valve is completely closed, however only up to max. operating torque (see table 3).

243 AVK GATE VALVES 55/30 Installation and Maintenance Instructions 4. Maintenance 4.1. General If the valve is installed according to AVK instructions, it is maintenance-free. However, every 4-5 years we recommend that you: 1) carry out a routine check of the valve for leaks around the stem and the flange gaskets. All seals will in the course of time be influenced by air and sunshine, and frequent and careful checks can reveal leaks. 2) adjust the bolts in the flange connections, as the compression of the flange gaskets may be reduced in the course of time and thus leaks may arise. Please observe the bolt torques and sequence table under section Replacement of stem sealing AVK valves are factory lubricated and maintenance-free. If it is neccessary to replace the stem seal the following procedure must be observed Before replacement Before replacement inform your supplier of the valve size. A gasket set will be delivered consisting of: - 1 wiper ring - 2 internal stem seal O-rings - 1 gland flange O-ring - 1 nylon bearing Disassembling IMPORTANT! Before replaceing the stem sealing the valve should be fully opened and not under pressure. This is done by turning the handwheel in opening direction until impact. It is very important to ensure that the wedge is fully open. 1) Unscrew the 4 gland flange bolts (pos. 3), lift out the gland flange (pos. 6) and pill off the stem. 2) Remove wiper ring (pos. 1), O-rings (pos. 2, 5) and bearing (pos. 4) carefully without damaging the gland flange Assembling 1) Clean the internal surfaces in the gland flange and check for damage. 2) Lubricate the new O-rings, wiper ring and plastic bearing all over with a thin layer of grease (Molykote 111). 3) Fit the wiper ring, plastic bearing and O-rings carefully in the cleaned gland flange (see figure). 4) Clean the stem and gland flange and check for damage. 5) Apply a thin layer of grease (Molykote 111) to the stem. 6) Fit the gland flange on the valve and fix with the 4 gland flange bolts (pos. 3). Please ensure that the O-ring (pos. 5) is not stuck between bonnet and gland flange. Tighten the bolts with a torque of 100 Nm. 7) The valve can be closed again by turning the handwheel in closing direction.

244 AVK POWERSAVER TM GATE VALVES 55/35 Installation and Maintenance Instructions 1. Introduction The AVK PowerSaver TM gate valve is a brand new patented valve generation with 60% reduction of the maximum operation torques compared to the norm for gate valves. However, the number of turns from fully open to fully closed position is only approx. 12% higher than for traditional valves. AVK PowerSaver TM valves therefore need less energy for operation (T-key, handwheel, actuator), which is both a handling and an economic advantage. The valve has a full and straight bore corresponding to the nominal diameter and can be installed independently of the flow direction. To keep the advantage of the full and straight bore vertical installation is recommended, however, flow/pressure limitations outlined below should be observed. The valves are 100% factory tested hydrostatically to DIN 3230 part 4, PN 10 and PN 16. The valves are suitable for installation under the following conditions: Flow velocity up to 5 m/sec. with max. 6 bar differential pressure across the closed valve. Flow velocity up to 0.5 m/sec. with max. 16 bar differential pressure across the closed valve. The valves comply with the general standard and market needs regarding installation, dimensions, materials, capacity and strength for large diameter valves, combined with the easy, cost saving operation of smaller valves. The valves have a standard gland flange to ISO Various optional extras can be supplied factory fitted or in kit form for retrofitting. See data sheet. A complete By-Pass system can be supplied factory fitted or in kit form for a later assembling. See chapter 2.3. The By-Pass system is not necessary for normal valve function, but can be used with advantage, if slow filling, or emptying of the pipe line is required. To minimise water hammer the recommended opening speed is min. 3 min. from fully open to fully closed position for valves with electric actuator. The AVK PowerSaver TM gate valves have many applications. IT IS THEREFORE IMPORTANT TO STATE OPERATING TEMPERATURE, PRESSURE, MEDIUM AND OPERATING CONDITIONS WITH ENQUIRIES/ORDERS, SO THE MOST SUITABLE VALVE WILL BE SUPPLIED FOR YOUR SPECIFIC PURPOSE. 2. Installation AVK PowerSaver TM gate valves are for above ground or chambered installation. The valves must be protected against freezing by insulation. Ice in the valve or valve bonnet may lead to damage or malfunction. 2.1 Gasket To ensure tightness it is important to select the correct type of gasket for the medium. 2 gaskets with the correct flange size must be used Bolts Table 1 Bolts DN Work pressure (bar) mm PN 10 PN 16 Quantity 450 M 24 M M 24 M M 27 M Installation and tightening The flanges should be clean and free of grease to fully tighten.

Before mounting of a By-Pass system the main valve must not be under pressure, and the medium must be under the level of the By-Pass flanges on the side of the valve. Preparation of the main valve The 2 blind flanges on the By-Pass bosses are removed and the gaskets and flanges of the valve are thoroughly cleaned for dirt and impurities. Preparation of a By-Pass system The 16 studbolts are screwed into the two cast iron bends, 8 pcs. in each, and the bends are fitted to the By-Pass valve, together with the mating gaskets (see drawing). The nuts are loosely fastened to ensure that the bends can move freely in relation to the valve. Mounting: The By-Pass system is mounted on the main valve together with the cleaned gaskets, and the previously removed nuts and washers are re-used for fastening. All nuts are in principle tightened as shown on the drawing under chapter The nuts are to be tightened with 100 Nm on the valve stem. The By-Pass system is now ready for use. 3. Operation The valve is equipped with an AVK PowerSaver TM which means that the valve can only be used as an ON/OFF valve. Therefore the valve must be FULLY opened before the AVK PowerSaver TM goes into function. Otherwise the valve will have an operating torque corresponding to a standard valve. The valve can therefore not be used as a control valve and at the same time provide the full advantage of the AVK PowerSaver TM function Right hand closing valves Closing IMPORTANT! From factory the valve is delivered with the wedge in almost closed position. Before the valve is put into service it must be FULLY opened to activate the AVK PowerSaver TM (see ). By manual operation the valve is closed by turning the handwheel clockwise until the valve is completely closed. Valves with actuators are closed by adjusting the actuator, so that the output shaft moves clockwise. The on/off torque switch should be adjusted, so that the valve is not operated by a higher torque than the operating torque (see table 3). Going to closed position the actuator shall be switched off by means of the on/off torque switch, not the limit switch Opening By manual operation the valve is opened by turning the handwheel anti-clockwise until the wedge is fully open, applying a torque of 100 Nm in the opening direction in the fully open position.
