Copper Rotary Check Valve

Category Check Valve Tag valve

Copper check valve adopts brass forging process, adopts swing structure, the valve opening and closing pressure is small, the fluid resistance is small, can effectively prevent the backflow of the medium.

Nominal Pressure	1.6 MPa
Nominal Dimension	DN15 -25
Applicable Temperature	0 ∼ 80^oC
Applicable Medium	Water

Process Description

Copper is used as material to form the basic shape of the valve. The valve then goes through the process of upsetting (forging), stress-relief annealing, shot blasting, machining, secondary annealing, ultrasonic cleaning, assembly, pressure testing, drying, and packaging for storage. With a final inspection, the valve will be packaged and sent out.

Features:

Installed in pipes to prevent media backflow
Automatically open and close, using the medium’s own pressure to open and close the valve
After the valve is fully opened, the flow is good, the fluid resistance is small, and the water pressure loss is small
Widely used in urban water supply field
