Frequently Asked Questions

Q What temperature range can these cryogenic ball valves handle?

These cryogenic ball valves are designed to operate in extreme temperature environments, ranging from as low as -196°C for cryogenic applications to standard industrial operating temperatures. The forged trunnion-mounted design reliably handles temperatures down to -46°C under high-pressure conditions.

Q What cryogenic fluids are these valves compatible with?

These valves are suitable for a wide range of cryogenic fluids, including LNG (Liquefied Natural Gas), Liquid Nitrogen (LN₂), Liquid Oxygen (LOX), and Liquid Hydrogen (LH₂). They are also applicable for other high-flow industrial fluids.

Q What safety features are included in the valve design?

The valves incorporate multiple safety features, including Double-Block-and-Bleed (DBB) functionality, Anti-Static protection, Fire-Safe design, Anti-Blowout Stem, and Low Fugitive Emission Packing.

Q What sizes and materials are available for customization?

The valves are available in a comprehensive size range from 2" to 36" (DN50 to DN900). Material options include A350 LF2, F316(L), Inconel 625, Hastelloy C, and more.

Q How are the valves tested before delivery?

Every valve undergoes stringent in-house cryogenic testing prior to shipment. This rigorous testing process verifies reliable, leak-free performance under the most demanding low-temperature conditions.

Q What is the advantage of a trunnion-mounted design over a floating ball design?

A trunnion-mounted design provides mechanical support to the ball via a fixed trunnion, which significantly reduces operating torque under high-pressure conditions. This offering enhanced durability, stability, and reliable sealing performance in demanding cryogenic environments.
