Document : PG00 Year : 09 Product Group 00 Cryogenic Butterfly valves Schema of Cryogenic (LNG, LPG) Butterfly valve Cryogenic valves are widely used throughout the world, from liquefaction plants, to liquefied gas carries, receiving tank terminals as well as peak shaving plants, in critical and hazardous service conditions down to a temperature of -96 degr. C. The materials used are austenitic stainless steels which maintains their strength at low temperatures The sealing system is a soft sealing system, fire safe type incorporating Kel-F ring inserts in the disc to ensure trouble-free operation. Also a metal seated double eccentric design is available (Not bubble tight). The valves have extended bonnet design to create an insulation gas column between the stem packing and the cold cryogenic fluid. This prevents hardening and shrinking of the packing and allows problem free operation. The butt-welded LNG valve has a side entry maintenance system to make replacement of the sealing ring possible without removing the valves from the pipeline. All valves are tested at cryogenic temperature by means of a special Manifold System creating a test environment comparible to the actual service conditions. Operations The following valve operation possibilities are available; Manual lever Operation Manual worm gear Operation Single or double acting pneumatic Operation Hydraulic actuator Operation Electric actuator 6 2 3 4 7 5 4 3 2 5 6 0 9 Page 3 09

Document : PG00 Year : 09 Product Group 00 Cryogenic Butterfly Valves Materials Specification for All materials supplied for the valve components are suitable for operation in LNG installations. Impact test is carried out on pressure retaining parts (body, bonnet, disc, studs and nuts) of cast material, according to ASTM Testing Procedures, with Charpy V Specimen, at -(negative) 96 degr. C Following minimum test results are required: average (on 3 specimen) not less than 3.5 kgm/cm2 minimum (on specimen) not less than 3 kgm/cm2 Fire Safe Design Valve has a fire safe construction. Sealing system has a Kel-f seal ring inserted into disc for sizes of 2 and larger. This Kel-f seal ring is replaceable and easy to replace for easy maintenance. In addition, soft sealing by Kel-f seal will perform an excellent and flexible sealing characteristic with minimum leakage at critical service condition at temperature of - (negative) 96 degr. C. In emergency of fire accident, even if this Kel-f seal ring is destroyed, sealing system can be secured by secondary metal to metal sealing. PHYSICAL PROPERTIES OF KEL-F HIGH COMPRESSIVE STRENGTH AND SUPERIOR CREEPING RESISTANCE KEL-F (polychlorotrifluoroethylene: PCTFE) has high compressive strength and creeping resistance, and is superior to TEFLON (polytetrafluoroethylen: PTFE), please refer to the attached data. Even under intense low temperature(liquefied H2 : -255 degr. C ), KEL-F has superior elastic memory and tendency. RESISTANCE AGAINST LOW AND HIGH TEMPERATURE KEL-F is applicable under intense temperature condition from -0 to + 0 degr. C WATER AND MOISTURE RESISTANCE KEL-F is superior characters of anti-moisture and complete water resistance; moisture absorption is nil. Even in water or high humidity conditions, KEL-F has perfect stability of dimensional and electrical characters. FACILITIES AGAINST IMPACT FORCE AND WEAR OUT KEL-F has superior facilities to resist impact force and wear out, and suitable for a long life service. MINIMUM SHRINKAGE Even at liquefied N2 temperature (-96 degr. C) condition, shrinkage and deformation are very small and ignorable. CONCLUSION KEL-F is the most suitable material for seal-rings of cryogenic valves by above mentioned reasons. Page 4 09

Document : PG00 Year : 09 Product Group 00 Cryogenic Tripple Eccentric Metal Seated Butterfly Valves Triple eccentric design principle Metal seated high pressure butterfly valves provide bi-directional bubble tight shut off, using tripple eccentric disc geometry. The valve shaft is off set against the seat and the centre line of the valve body respectively. The seating edges are machined with a continuously changing slope from an angle on top of the oval seat ring to an angle at the opposite side. This geometry ensures that the seat ring stays clear of the seat except at the final shut off position, resulting in long life seat, due to minimum wear. STEM CENTER LINE SEAT CENTER LINE VALVE CENTER LINE STEM CENTER LINE Metal to metal seat Various disc seals are available to comply with each temperature and pressure service applications. Solid metal seals are often used for temperatures above 50 and up to 5 degr. C and low temperature service. Laminated metal seals consist of stainless steel with intermediate layers of graphite or ceramic fiber. The laminated seal is secured to the disc with a bolted-on stainless steel clamp ring, and is easily accessible for replacement. The graphite laminated seal is suitable for temperatures between -40 and +650 degr. C in general. The seal leakage meets API 59 or API 6D. The solid metal seated valve can be operated in a temperature range of -253 to +5 degr. C. Valves for cryogenic application are provided with extended stems.

AA - Nominal outside diameter for cast steel valves, inches (see table). B - Nominal inside diameter of pipe, inches. t - Nominal wall thickness of pipe, inches. C - A-0.03 -.75t - 0.00. Regardless of tolerances specified for dimensions A and B, the thickness of the welding end shall never be less than 7 /2 percent of the nominal thickness of the pipe. For complete dimensions, details, and tolerances, see ANSI B 6.25. OUTSIDE CONTOUR When the thickness at the welding end of the valve is greater than that of the mating pipe, and when the additional thickness increases the outside diameter, a taper weld having a slope not exceeding :3 may be employed, or the greater outside diameter may be extended back in a manner within the maximum slope lines indicated in Figs. A and B. The transition shall be of a shape avoiding sharp re-entrant angles and abrupt changes in slope. The profile of the outside contour shall be at the manufacturer s option provided above conditions are met. INSIDE CONTOUR For a joint without a continuous backing ring, the inside contour of the valve end shall be bored to a diameter B to a depth of t. The inside diameter of a valve end beyond this mackined surface may be either larger of smaller than the inside diameter of the pipe. The transition shall be of a shape avoiding sharp re-entrant angles and abrupt changes in slope. See Figs. A and B. (Transition shape also applies to Fig. 2 and 3.) For a joint with a continuous rectangular backing ring, the inside contour of the valve end shall be a straight bore of diameter C, in. deep. This depth is based on a backing ring in. wide; but if a wider ring is used, the depth shall be increased to provide the / in. minimum end clearance indicated. See Fig. 2. For a joint with a continuous tapered backing ring, the inside contour of the valve end shall be taperbored from diameter C at the lip, taperling at 0 deg. to a taper length of 7/32 in. minimum. Beyond this taper length, the bore may be a straight diameter of dimension B, or the 0 deg. taper may be extended to the inside port diameter. See Fig. 3. See Figs. A and B for Outside Contours.
