Cryogenic check valve DN40 PN50 under welding

CADUCEUS cryogenic check valves with innovative design are used to prevent the change of medium flow in the process system, ensure its stable operation both in normal operation mode and in case of emergency pressure drop in one of the pipeline sections.

This type of protective pipeline fittings is made of stainless steel and materials resistant in cryogenic environment at working pressures and temperatures, which guarantees tightness of the product and long service life.

A wide range of models allows to choose valves for working pressures up to 63 bar, nominal diameters from 20 to 40..
