Description
High 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.
