Low Temperature Welded Stainless Steel Check Valve DN25mm 32.0MPa for Cryogenic Applications -196℃ to +80℃

Low temperature welded type stainless steel check valve designed for cryogenic applications with high pressure capabilities up to 32.0MPa and temperature range from -196℃ to +80℃.

This valve operates through directional media flow control. When media flows in the designated direction, the valve disc opens automatically. During reverse flow, the valve disc seals tightly against the valve seat through combined disc weight and media backpressure, effectively preventing backflow.
