 Safety valve 5.7A25 is an economical and compact high-pressure safety valve with good set pressure control. This valve is a special valve that is normally closed under external force. When the pressure of the medium in the equipment or pipeline rises beyond the specified value, the medium can be discharged outside the system to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. A safety valve is an automatic valve mainly used in boilers, pressure vessels, and pipelines. Controlling the pressure to not exceed the specified value plays an important role in protecting personal safety and equipment operation. The injection safety valve can only be used after the pressure test.
