Materials of Construction Body End Cap Aluminum alloy, extruded according to ASTM 0, anodized according to UNI 22. Die-Cast in aluminum alloy ASTM B179, painted with epoxy-polyester powder. Pistons Die-Cast in aluminum alloy ASTM B179. Pinion Pinion Bearings Nickel-plated steel. Acetal Resin (LAT LUB 71 20T) + 20% PTFE. Screws Stainless Steel AISI 0. Springs Seals Standard Grease Optional Grease Precompressed cartridge, painted with epoxy powder. Nitrile rubber NBR (VITON or EPDM on request). MoS2. Molykote. Optional Corrosion Protections Coating with Chemical Nickel Having High Phosphorous Content Nickel deposits without electricity are produced by the chemical reduction of nickel in metallic substrate, without using electricity. Dead holes, threads, grooves, recesses or inside surfaces receive the same plating quantity as the sharp angles, the corners or the flat surface (20-0 um). The standard degree is approximately - Rockwell C and offers a good resistance to corrosion in salty fog. Please take care not to damage the surface by scraping, since this exposes the basic material to corrosion. (On request, the pistons may also be nickel-protected.) Strong Anodized Protection The electrical process produces a thick anodized coating up to 0 microns. The resulting part resists corrosion from dipping and sprays of sodium and chlorine and also corrosive cracking stress. The oxide coating is perfectly adherent and will not chip, even after sudden temperature changes or at temperatures equal to the aluminum melting point. Aluminum oxide is one of the hardest known materials: - Rockwell C. Epoxy-Polyester Coating Epoxy-coating is a deposit of powders on clean and sandblasted pieces. The chemical process is easily kept under control and after coating, the pieces must be subjected to heat treatment. Epoxy painting of actuators is advised where environment is strongly aggressive. With a normal thickness of 200/20 microns of epoxy coating, resistance to salty fog exceeds 1,000 hours. With the exception of certain solvents, epoxy coating resists acids and alkali, and also has a good resistance to UV rays. In order to retain its properties, the coating must not be scratched. (Springs have this standard coating.)

Actuation Sizing Guide The seat material used, media, temperature, frequency of operation and criticality of the valve s operation are all important factors in calculating the actuation needs of a given valve. The information provided below should be considered as a guide only and must be adjusted according to experience and judgement. Proper actuator selection is required to prevent valve or process equipment damage as well as proper valve operation. In general, we can say that valve torque results from the friction between the ball and seats as well as the stem and stem seals. Valve Torque The torque requirements of Sharpe Ball Valves will vary depending on several factors. Seat design and material Sharpe seats are designed to ensure consistent sealing and low torque. The seat friction force depends on the seat material and the applicable service factor multipliers shown in the chart below. Stem Seal Torque results from the stem contact with stem seals. Packing materials affect torque. Stem seal torque is a high percentage of overall torque especially in small valve sizes. Service Conditions Differential Pressure Minimum and maximum pressures Frequency of Operation Stuck valve torque Media Influence Slurries, dry gases, oils Temperatures Minimum and maximums Cycle Time Line hammer, process requirements Instrument Air Supply Peak demand pressure availability Media and Service Factors To establish minimum torque requirements, multiply valve torque by the following application media and service factors. Media Factors Multiplier Clean particle free, non-lubricating 1.00 (water, alcohol or solvents) Clean particle free, lubricating oil 0.80 Slurries or heavily corroded and contaminated systems 1.0 to 2.00 Gas or saturated steam, clean and wet 1.00 Gas or superheated steam, clean and dry 1.0 Gas, dirty unfiltered e.g. natural gas, Chlorine 1.20 to 1.0 Service Factors Multiplier Simple On and Off Operations 1.00 Throttling 1.20 Positioner Control 1.0 Once per day session 1.20 Once every two days 1.0 or more or plant critical

Ball Valve Ball valve construction concept is based essentially on a polished ball (including a through port) contained in two seats (upstream and downstream). The ball rotation allows the flow or stops the flow through the valve. Differential pressure between upstream and downstream pressure forces the ball against the downstream seat (floating ball). In this case, the valve torque is generated by the friction between ball and seat and also between stem and packing. As shown in the diagram to the right the highest torque point is when, in presence of pressure, the valve is in the closed position, and passes to the open position (breakaway torque). BALL VALVE TORQUE 100% 70-80% 2-0% Torque % CLOSE Valve Rotation OPEN Butterfly Valve Butterfly valve construction concept is based essentially on a disc fixed on an axis, which in the closed position, is completely contained by the seat. The open position is obtained when, with a rotation, the disc (through its stem) becomes parallel to the flow. On the contrary, the closed position is obtained when the disc is perpendicular to the flow. In the case of the butterfly valve, the torque is generated by the friction between the disc and the seat, by the stem packing and also by the differential pressure that forces on the disc. The highest torque point, as shown in the diagram, is in the closed position, and only after a small rotation it is considerably reduced. BUTTERFLY VALVE TORQUE 100% 1-20% Torque % CLOSE Valve Rotation OPEN Plug Valve Plug valve construction concept is based essentially on a male (plug) contained in a female cone (seat). The plug provides a through port in one direction and with its rotation into the seat the opening and closure of the valve is obtained. The torque is usually not influenced by the flow pressure, but is generated essentially by the friction between the seat and the plug, during the opening + closing cycle. As shown in the diagram to the right, the highest torque point is in the closed position and remains high for the rest of the operation, because the torque is not influenced by pressure. PLUG VALVE TORQUE 100% 80-90% Torque % CLOSE Valve Rotation OPEN

Double Acting Actuator () In the double acting actuators, the control pinion rotation and its reversal are obtained by reversing the supply to the two input ports. The output torques obtainable mainly depend on the cylinder diameter and the supply pressure; by increasing one or both factors, the available torque also increases. The friction should usually be neglible. As shown in diagram A, the torque of a actuator is constant throughout the entire rotation and relevant reversal. The advised safety factor, in addition to the valve maneuvre torque, is approximately 20%. START/ END 0º º 90º END/ START Diag. A *Select the actuator size whose torque output at given pressure exceeds the valve torque and application factor. Spring Return Actuator () In these type of actuators, which utilize springs for reversing the rotation of the control pinion, the output torque depends not only on the cylinder diameter and the supply pressure, but also on the presence of the springs, which should be compressed to guarantee the return. As shown in diagram C, the available torque at 0º progressively reduces during the rotation due to the springs compression. On the contrary, as shown in diagram D, the torque starting from the 90º position constantly decreases until 0º because of spring extension. Owing to the higher friction present, the safety coefficient advised in this case is approximately 2%. START 0º º 90º Diag. C END *Select the actuator whose torque ouput at 0º and 90º at a given air pressure exceeds the valve torque. START END Recommended Spring Positioning 0º º 90º Diag.

Operation DOUBLE ACTING (TOP VIEW) Air supplied to Port A moves pistons apart and toward end positions with exhaust air exiting at Port B (a counterclockwise rotation is obtained). Air supplied to Port B forces pistons toward center with exhaust air exiting at Port A (a clockwise rotation is obtained). SPRING RETURN (TOP VIEW) Air supplied to Port A forces pistons apart and toward end position, compressing springs. Exhaust air exits at Port B (a counterclockwise rotation is obtained). Air or electric failure allows springs to force pistons toward center position with exhaust air exiting at Port A (a clockwise rotation is obtained). Reverse Rotation Upon request, the pistons can be inverted in order to obtain a clockwise rotation when the air pressure is applied to Port A. Other types of assembly are possible: for any information, please contact SHARPE. Quick Operation Actuators Upon request, SP-Air Series actuators can be specially prepared for fast response operations.
