Check Valves
1/8" - 2" NPT
0 - 4500 Psig

Description of Check Valves

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 the O'ring and spring from over-stress fatigue. Zero external leakage is achieved by utilization of a static O'ring seal with TFE backup ring. When specified with the proper seal material, these valves are ideally suited to cryogenic system applications.

PROPER COMPONENT SELECTION - When specifying a component, the total system design must be considered to ensure safe and trouble-free performance. Intended component function, material compatibility, pressure ratings, installation, environment and maintenance are the responsibility of the system designer.
