Spring check valves for in-line use in cryogenic applications

Spring check valves are smaller check valves that are some of the most commonly used supplemental units for a fluid system. Their smaller frames make them suitable for horizontal in-line installation, after a pump, to prevent damage from reversed transmission of pressure and flow.

Product description

Compared to other types of check valves, these tolerate higher pressures with the same back-flow prevention functionality.
