Valves
Check Valves
Our check valves let flow pass in one direction and stop it reversing, protecting pumps, instruments and equipment from backflow. A back-stopped poppet and blowout-resistant seat reseal reliably every time flow stops, and cracking pressures from 0.02 bar to 1.2 bar let you match the valve to the system.
