Product discription:
Size: 2"--32" or DN50--800mm
Pressure: PN1.0--2.5MPa or Class 150--300lbs
Material: Cast iron, cast steel, carbon steel, stainless steel.
Diaphragm type: DN50-DN350

Proveded with a non-return valve to control opening and closing speed. It can be adjusted to optimal opening and closing speed to cater for working conditions when pump starts or stops running.

First close main valve by 90% before stopping pump motor, and then close the rest 10%, thus to successfully avoid the production of water hammer and slamming.

Note: We accept design and manufacture of various non-standard valves and arrange production according to users' supplied drawings and samples
