Shanghai Metal Corporation is a professional manufacturer and supplier of Closed Spring Loaded Full Bore Type Safety Valve with high quality and reasonable price.
A spring-loaded safety valve refers to a valve that relies on the elastic pressure of a spring to lock its valve or plunger seals. Once the pressure in the pressure vessel is abnormal, the high pressure generated will overcome the spring pressure of the safety valve. Therefore, the locking device is pushed open, forming a pressure relief channel to release the high pressure. According to the different opening heights of the valve disc, it can be divided into two types: full lift and micro lift. Full lift type has a large discharge capacity and good rebound force, suitable for liquid and gas media, while micro lift type is only suitable for liquid media.
Spring type safety valves are suitable for equipment and pipelines with steam water and other media working at temperatures ≤ 350 ℃. As an over pressure protection device.
