Safety valves and back pressure valves are essential protective and regulating components in fluid pipeline systems, widely used in chemical, water treatment, environmental protection and other industries. They can effectively stabilize system pressure, prevent overpressure damage to pumps, pipelines and related equipment, avoid medium backflow, and ensure safe, stable and continuous operation of the whole system.
Features
1. Release pipeline pressure to ensure stable system pressure;
2. Protect pump safety and the normal operation of the system;
3. Used together with pulse dampers to reduce water hammer damage to the system and achieve excellent low-vibration regulation effect;
4. Reduce peak flow fluctuations and protect the pipeline system from pressure surge impact;
5. The diaphragm adopts advanced PTFE + rubber composite technology, which is suitable for almost all corrosive fluids with reliable sealing and no leakage.
