The CP valve is an oscillating flap wafer check valve (without spring) for assembly between DIN, ANSI, JIS, etc. flanges.
Its main feature is that the fluid passage diameter is off-centre from the pipe’s axis, meaning that the flap opens further, leading to lower head loss.
Available in standard materials such as Carbon Steel, AISI 316L, BRONZE, BRONZE ALUMINIUM, as well as special alloys AISI 904L, SUPERDUPLEX 5A, SUPERDUPLEX 6A, DUPLEX 4A, etc.
