Product Description
Body material: ASTM A182 F316
Cryogenic Service
Cr yogenic valves are demanded widely for application between -196¡æ and -50¡æ, including LNG that is fast becoming a better alternative source of clean energy. VIZA develops its cryogenic floating (Series FY) and Trunnion mounted (Series TY) ball valve accordingly.
Standards
ASME B16.34, ASME B16.5, API 6D, BS EN ISO 17292, BS 6364, Shell MESC 77/200, BS EN 12266, Shell MESC 77/306
Applications
Ethane: -89¡æ
Ethylene: -104¡æ
Methane: -162¡æ
Liquefied Natrual Gas (LNG): -162¡æ
Oxygen: -183¡æ
Nitrogen: -196¡æ
Cryogenic Test
Valves can be tested by in house testing facility and the report can be provided per request.
General Features
Extension bonnet gives enough vapour space to maintain the stem packing at a temperature high
enough to protect the stem packing against malfunctioning due to freezing;
Cavity pressure relief;
Low operating torque for smoother operations;
Blow-out proof stem, anti-static device and fire safe design;
Double block & Bleed (Series TY);
Low fugitive emission compliance.
