Check Valves
316 stainless steel inline check valves rated to 6,000 psi WOG that stop reverse flow on instrument, injection and process lines.
About Check Valves
Trilogy inline check valves allow flow in one direction and stop reverse flow, protecting pumps, instruments and injection systems from backflow. A spring-loaded ball seats against a Viton O-ring for a positive seal, and the valve opens at a low 8 to 10 psi cracking pressure.
The 316 stainless steel body is rated to 6,000 psi WOG, with an NPT female inlet and male outlet for straightforward inline installation. Flow direction is marked on the body.
