CHECK VALVES 316 Stainless Steel Check Valves

By preventing reverse flow, check valves can be used as one-way valves, injection valves, or to prevent backflow. Check valves allow flow in one direction, automatically prevent back flow when process fluid in the line reverses direction, and will work even if the system loses air or electricity. Installed in the process pipe, check valves are flow sensitive and rely on the line fluid to open and close. The internal ball or poppet functions as a positive shutoff to ensure process fluid does not go back up the line. Check valves can be installed vertically or horizontally. Robust construction ensures reliability in the rigorous service of municipal and industrial applications.
