Product introduction:

ANSI swing check valve is to rely on the media itself, the flow of automatic open and close the valve to prevent the media backflow valve, also known as the non-return valve, check valve, reversing valve, and back pressure valve. Check valve is an automatic valve, the main role is to prevent the backflow medium to prevent the pump and drive motor reversal, as well as the container medium discharge. Check valves can also be used to the pressure may rise to exceed the system pressure of the auxiliary system supply pipeline. Check valves can be divided into swing type check valves (depending on the focus of rotation) and lift check valve (along the axis of movement).

Parameter drawing:

Annex 1: 4~6H150-CF8M

Annex two: 50-600 check valve (RF 150Lb)

Annex three: parameters

Product features and advantages:

1. valve flap for swing type, flow channel through, horizontal pipeline vertical pipe can be installed.

2. Rocker pin shaft by loading type structure, to reduce the external leakage faults. 3. Valve cover bolt connection, high pressure level is greater than class 600Lb, flange pressure from the sealing structure, makes products 4. Volume light weight, reliable sealing. Standard (fire, anti-static)

Application:

Suitable for oil, chemical, chemical fertilizer, chemical fertilizer, power industry and other operating conditions of the pipeline, cut off or switch on the pipe
