Product Description

Key Features

Trunnion Mounted Ball Design

Protects upstream and downstream seats from excessive load for long service life.

Extended Stem with Cryogenic Neck

Prevents cold transfer to packing and actuator, ensuring anti-blowout and stem retention under pressure.

Lip Seal Design

Enhances sealing reliability significantly under extreme low-temperature conditions.

Worm Gear Operator

ISO 5211 mounting reduces torque for precise control; compatible with 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.

16inch 900LB F316 Cryogenic Ball Valve

Frequently Asked Questions

What media is this cryogenic ball valve suitable for?
The valve is specifically designed for cryogenic media such as LNG (Liquefied Natural Gas), liquid nitrogen, liquid oxygen, and other extreme low-temperature fluids.
Why is the stem extended on this valve?
The extended stem (cryogenic neck) moves the stem packing away from the cold fluid, preventing it from freezing and ensuring a reliable seal and smooth operation of the actuator.
What are the benefits of the Trunnion Mounted design?
It provides a fixed ball position with floating seats, which reduces operating torque and minimizes wear on the seats under high-pressure conditions.
Is the F316 stainless steel material standard?
Yes, forged ASTM F316 is used for its superior toughness and corrosion resistance at sub-zero temperatures, though other materials can be customized upon request.
Can this valve be automated for remote control?
Absolutely. The valve features ISO 5211 mounting pads, allowing the manual worm gear to be easily replaced with electric or pneumatic actuators.
Does this valve include fire-safe features?
Fire-safe, anti-static, and emergency sealing features are available as optional upgrades to meet specific safety and project requirements.
