Key Features
Trunnion Mounted Ball Design
Protects upstream and downstream seats from excessive load for long service life.
Extended Stem with Cryogenic Neck & Anti-Blowout
Prevents cold transfer to packing and actuator, and ensures stem retention under pressure.
Lip Seal Design
Enhances sealing reliability under extreme low temperatures.
Worm Gear Operator with ISO 5211 Mounting
Reduces operating torque for precise control; can be upgraded to electric or pneumatic actuation.
Product Details
This 16-inch Class 900 cryogenic trunnion mounted ball valve is engineered for reliable shut-off and flow isolation in extremely low-temperature, high-pressure applications. Made from forged ASTM F316 stainless steel, it delivers excellent toughness, corrosion resistance, and sealing performance in cryogenic service.
The trunnion-mounted ball reduces operating torque, while the extended stem isolates the packing from cold media for long-term sealing reliability. A heavy-duty worm gear operator ensures smooth control in large-diameter, high-pressure pipelines.
Suitable for LNG, liquid nitrogen, liquid oxygen, and other cryogenic media. Sizes, materials, and pressure ratings can be customized to meet specific project requirements, with optional fire-safe, anti-static, and emergency sealing features available on request.
