Our company is providing superlative Cryogenic Valve which is widely appreciated owing to its dimensional stability, ability to regulate the flow of liquids and gases, and durability. This valve is made in our state of the art manufacturing division with the incorporation of cutting-edge techniques, and therefore it is a sturdy and highly functional valve. Its use in industries like pharmaceuticals, chemicals, marine, etc, enhances the efficiency of fluid processing mechanism. Moreover, this Cryogenic Valve can be availed from us at the market leading price.
Cryogenic Extended Bonnet forged Valve OS&Y Rising stem Bolted Bonnet API 602, BS 5352,Socket weld ,butt weld, Screwed end ANSI B16.25,ANSI B16.11,ASME B16.34 Manual Hand Wheel All basic design features of USMANI forged steel valves outlined in this catalog are adapted to special service conditions at cryogenic temperatures.
· Extended bonnets with sufficient gas column length, usually specified by customer, are supplied for all valves to keep stem packing at sufficient distance away from the cold fluid to remain functional.
· Solid: Stellite 6 wedges on 1 ⁄2 – 2” valves operate with no galling in cryogenic service.
· Kel-F inserts (optional) for globe, piston, and swing check discs.
· Cleaning: All cryogenic valves are thoroughly degreased and cleaned and pipe ends are sealed to prevent contamination.
· Body: and bonnet: Austenitic stainless steel forgings used for bodies and bonnets offer excellent impact strength, minimal heat loss and protection against corrosion.
· Stem: To reduce galling, stems are made from advanced Nitronic 50 (grade XM-19 A479) with high tensile even at extreme low temperatures, excellent low friction and galling-free movement at points of stem contact.
· Wetted parts: All Austenitic Stainless Steel and Stellite 6.
· Yoke bushings: Bronze.
· Packing: Teflon or other plastic packing protected from freezing by a column of insulating gas.
· Seating faces: Stellite 6 is used to prevent seizing and galling. When extremely tight shutoff is required, globe and check valves may be supplied with Kel-F, Teflon or other soft inserts.
· Bolting: Strain-hardened Austenitic Stainless Steel.
· Lubrication of yoke bushing nut (yoke nut): Exxon: Nebula EPI Shell: Darian EPI Lubriplate No. 930-AA or 930-AAA
