    Product Description

    The safety valve mainly used in boilers, pressure vessels and pipelines, control the pressure does not exceed the specified value,plays a role of safety protection in the system. When the system pressure exceeds the specified value, the safety valve opens, and a part of the fluid in the system is discharged into the pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not have an accident due to high pressure.Safety valve plays an important role in protecting personal safety and equipment operation. Our safety valves are pressure tested before they are put into service.
