High flow, bubble-tight, low pressure drop check valve suitable for many 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. External body seal is achieved by the utilization of a static elastomer O-ring seal with PTFE backup ring. Available in 1/8" – 2" NPT, rated to 4500 PSIG.
