Safety valve (also known as relief valve) is opened and closed automatically according to the working pressure of the pressure system. Safety valve is generally installed on the equipment of closed system or pipeline to keep the system safety. When the pressure in the equipment or pipeline exceeds the setting pressure of the safety valve, it will open automatically and relief the pressure to ensure that the medium pressure in the equipment and pipeline is under the setting pressures the equipment and pipeline can work normally to avoid accidents and losses.
- With Diaphragm structure spring and the pressure will be adjustable.
- The medium contacting parts are only the lower valve body and the diaphragm and they are assembled with sealing rib which has good sealing effect and high sensitivity
- EPDM lining PTFE with Cloth type diaphragm has a very good sealing effect and long service life
- The PTFE type diaphragm has a very good performance in high temperature resistance corrosion resistance.
