Key benefits

• Unidirectional flow – wafer-type design ensures free flow in one direction and tight shut-off in the opposite.
• High-quality PVC – material resistant to chemicals, oxidation, and corrosion, extending valve life in aggressive environments.
• Compact wafer design – slim build simplifies installation between two flanges without additional adapters.
• Solvent-weld ready – ends designed for permanent bonding with PVC pipes; no threading or welding required.

Description

The Era wafer check valve (flangeless) is a key component for any water system requiring backflow protection – including water supply networks, drainage systems, water treatment stations, and industrial process loops. Thanks to its hinge- and spring-free design, the valve opens under forward flow and automatically closes under back pressure, eliminating the risk of contamination and pump damage.

Model 17667 is made of high-quality PVC (polyvinyl chloride), which is chemically resistant to corrosive substances, oxidation, and UV radiation. The glossy gray finish (RAL 7035) not only looks clean but is also easy to maintain. The 315 mm nominal diameter allows installation in standard pipes of the same size.

The valve is supplied without flanges or mounting bolts – ready to be installed on flanges matched to your specific system. Connection is made via solvent welding, providing a durable, leak-tight joint without the need for gaskets. Ideal for PVC systems requiring quick and reliable backflow prevention.
