Spring Loaded Pressure Safety Valve

With our sound facilities, we are engaged in manufacturing, exporting, distributing, trading and supplying a massive gamut of Spring Loaded Pressure Safety Valve in Wenzhou, Zhejiang, China.

DIN Standard Safety Valve Features:
Safety valves were first used on steam boilers during the industrial revolution. Early boilers without them were prone to accidental Exploson.
Safety valves also evolved to protect equipment such as pressure vessel (fired or not) and heat exchangers. Safety valve term should be limited to compressible fluid application (gas, vapor, steam).

The two general types of protection encountered in industry are thermal protection and flow protection.

For liquid-packed vessels, thermal relief valves are generally characterized by the relatively small size of the safety valve necessary to provide protection from excess pressure caused by thermal expansion. In this case a small valve is adequate because most liquids are nearly incompressible, and so a relatively small amount of fluid discharged through the relief valve will produce a substantial reduction in pressure.

Another outstanding advantage of the valve is: a valve body can be installed with many pilot valves, to realize the temperature control, upper stream pressure control and long-distance switch control as well as pressure regulating.
