Series CV Check Valve
Brand: Generant IncHigh flow, zero leak, low pressure drop check valve suitable for most fluid and gas applications.
Fully guided poppet with free floating O-ring design is extremely tolerant of particulate contamination. A metal to metal positive stop in both the open and checked position protects O-ring and spring from over-stress fatigue.
Zero external leakage is achieved by the utilization of a static O-ring seal with PTFE backup ring. When specified with the proper seal material, these valves are ideally suited to cryogenic system applications.
