Safety Relief Valves

Safety valve is a part for releasing the pressure generated in the piping. There are a wide variety of items such as a type that can drain water, such as a relief valve of a hot water heat exchanger, and a universal type that can handle oil and steam in addition to water. A variety of safety valves, such as a sealed structure that does not leak easily and a type that uses a synthetic rubber diaphragm with excellent heat and water resistance, are available. It is an indispensable item for a wide range of work sites such as repairing water heaters and piping work for boilers.
