    Safety Relief Valve is a device used to protect the heating or water supply system from possible water hammers and excessive pressure of the working medium. The use of safety valves is a prerequisite in any technological pipeline creation. The absence of a safety relief valve can lead to the breakdown of engineering and plumbing equipment, water leakage from the pipeline system, and injury to people.

    Depending on the energy source, valves can be of the following types:

    · Indirect valve,

    · Direct pressure safety valve.

    In addition, this valve can differ in the method of immersion: spring or cargo, in the release of excess fluid method valves of closed or open action, also from the capacity: safety valve of the small, medium, and full lifting.
