Joint End : Socket: ( ANSI, JIS, CNS, DIN);

                  Threaded: (NPT, BSPT, BSPF);

                   Working Pressure:150PSI

Description:

Back pressure valve that there is a certain pressure due to the function of the valve, and the pressure can generally be adjusted. It can be used to control the flow of all kinds of fluids such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive medium. The opening and closing part is a disc shaped valve plate rotated around its own axis in the valve body so as to achieve the purpose of opening or closing or regulating. The main function of the pipe is cut off and throttling. The most commonly used systems are fluid metering dosing system, hydraulic control system, chemical reaction condition, state critical state control and so on. Basically, it can be divided into two parts: regulation and overflow.

Selection Guide

When selecting backpressure valves, the parameters and data must be determined.

1, the caliber of the required backpressure valve is usually the outlet diameter of the pump.

2. The range of pressure required to be set;

3. Material is considered from the nature and temperature of the fluid conveyed. Conventional materials are: PVC, 304, 316, 316L stainless steel, carbon steel, etc.

4, In some systems, such as food and drinking water production systems, some pipelines may have special requirements for connection. Common connections include internal thread, flange and hose connection.
