Frequently Asked Questions

Common questions about valve design, performance, and automation for this application.

What are cryogenic valves and where are they used?

Cryogenic valves are designed for applications involving extremely low temperatures. They may be used in LNG facilities, industrial gas plants, liquid nitrogen systems and other low-temperature processes. Selection depends on the fluid, minimum design temperature, pressure and required sealing performance.

Which valves are used in cryogenic applications?

Cryogenic ball valves, gate valves, globe valves and check valves may be used depending on the application. The selected valve must be designed and qualified for the specified low-temperature conditions, pressure range, fluid properties and isolation requirements.

What is the difference between a standard valve and a cryogenic valve?

A cryogenic valve is designed or qualified to operate under specified low-temperature conditions. Its materials, seats, seals and construction must maintain suitable mechanical and sealing performance at the required temperature. A standard industrial valve should not be assumed suitable for cryogenic service without verification.

Which materials are suitable for cryogenic valves?

Material selection depends on the minimum design temperature, pressure, fluid and applicable design requirements. Austenitic stainless steels are used in many cryogenic applications, but the suitability of the body, trim, bolting, seats and seals must be verified for the specific service.

What is an extended bonnet in a cryogenic valve?

An extended bonnet increases the distance between the cryogenic fluid and the valve stem packing area. This helps limit cold transfer to the packing and supports reliable stem sealing. The required bonnet extension depends on the valve design, operating conditions and manufacturer's specifications.

Which valves are suitable for LNG applications?

Cryogenic-rated ball valves, gate valves and other suitable designs may be used in LNG systems. Selection depends on LNG temperature, pressure, valve size, leakage requirements, material suitability and applicable project standards. Confirm the specific valve's qualification for LNG service.

Can cryogenic valves be used for liquid nitrogen and liquid oxygen?

Yes, where the valve is specifically suitable for the intended fluid and operating conditions. Liquid nitrogen and liquid oxygen have different service requirements. Liquid oxygen service requires particular attention to oxygen compatibility, cleanliness and ignition hazards, with suitable design and qualification verification.

How can leakage be minimized in cryogenic valves?

Select a valve with suitable low-temperature materials, seats and sealing arrangements. Consider thermal contraction, operating cycles and the required leakage performance. Follow the manufacturer's installation and maintenance instructions and verify any specified cryogenic leakage test requirements.

Which standards should be checked when purchasing cryogenic valves?

Review the applicable project specifications and valve design, material and testing requirements. BS 6364 is a standard associated with valves for cryogenic service and may be relevant depending on the application. Confirm the required edition, scope, testing and compliance documentation for the specific valve model.
