4" CVG01 Grooved-end Swing Check Valve 365 psi

Style CVG01 Grooved-end Swing Check Valve is a product developed under innovative engineering and rich experiences. CVG01 is an UL/cUL listed and FM approved non-return valve which permits water flow in one direction and prevents flow in reverse direction. This function is realized by a spring loaded stainless steel clapper with an EPDM rubber facing and an broadened bronze seat, to provide a long service lime and leak-free sealing. It is widely used with various configurations in fire sprinkler systems, fire department connections, gravity pressure tank or by-pass connections etc.
