Plastic Check Valves for Water Conditioning

This specialized line of plastic check valves has been designed for use with iron filters in the water conditioning industry, engineered for installation on Clack and Pentair control valves. We use a one-piece, NSF Celcon molded body and spring retainer. The plastic line comes standard with a Buna-S rubber poppet, an extremely durable compound for use with potable drinking water. All other internal components of stainless steel. Each valve is tested at very low air pressure for backflow prevention. All valves are 100% American-Made and built to last.
