Worm gear low-temperature LF2 American standard flange ball valve

DWQ341F Worm Gear Low Temperature Flange Ball Valve

This product adopts worm gear operation and low-temperature flange ball valve structure. The series diameter range is DN15-DN1000, pressure is PN16/Class150, and material fields include LF2, LCB, and F304. The actual minimum design temperature must be confirmed based on the material condition, valve design, and project specifications.

Low temperature materials cannot be solely judged by their brand name

LF2, LCB, and F304 belong to different material systems. The actual pressure bearing material needs to be checked based on the minimum design temperature, material specifications, and pressure temperature conditions. The temperature capability of one material cannot be applied to other configurations.

Does cryogenic treatment use a fixed process?

Whether cryogenic treatment is required, as well as the treatment temperature, insulation time, cycle times, and applicable parts, should be determined according to the specific product manufacturing process and project specifications.

Special media such as liquid oxygen and liquid hydrogen

If it involves oxygen medium, hydrogen medium or other special low-temperature media, it is also necessary to confirm material compatibility, cleaning and degreasing, anti-static and project safety regulations, and cannot be directly identified as applicable based solely on the name of "low-temperature ball valve".

Frequently Asked Questions

Do all low-temperature ball valves need to be processed in - 196℃?

This cannot be uniformly stipulated, and should be implemented according to specific materials, product processes, and project requirements.

Can LF2, LCB, and F304 be interchanged freely?

No, the selection should be based on the minimum design temperature, pressure, and project material specifications.

Can this ball valve be directly used for liquid oxygen?

It cannot be judged solely based on low-temperature materials, but also needs to meet oxygen medium compatibility, cleaning and degreasing, and corresponding safety requirements.
