Back pressure valve is also called the pump protection valve, which is used as a special pressure Control Valve, which is used as a special pressure control valve, and is often matched with the automatic recirculation, used in the pump protection system. PVC Back Pressure Valve are also widely used in other control valve systems. The upstream pressure is controlled by the back pressure valve to achieve the pressure value set by the plant or the pressure value required by the system, so as to prevent vaporization and cavitation. Carefully match the process conditions between the automatic recirculation valve and the back pressure valve to ensure the best protection of the pump, and provide a guarantee for the long-term and stable operation of the system.
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. What kind of material is needed? Generally speaking, it is considered from the nature and temperature of the fluid conveyed. Conventional materials are: PVC, 304, 316, 316L stainless steel, carbon steel, etc.
4, import and export connection mode, this general requirement is less. However, 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.
Product Features of Back Pressure Valve:
1, Compact structure and stable performance
2, Easy installation and debugging
3, Sensitive reaction and good reproducibility
4, Selective large size range DN10mm DN100mm
5, Small pressure difference by specially designed flow structure to avoid forming a closure
6, Easy to set the working pressure by regulating device
7, Installed in the bypassas overflow valve use
8, Used as anti siphon valve to prevent gravity under static conditions.
