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.

Features of our safety relief valve
We as top safety relief valve suppliers in China, produce top-quality products. Our product consists of;
· Brass or bronze are in use for the metal case.
· Safety mechanism with steel spring and protective safety handle
· Locking element: spool or plate
· Bellows for hermetic connection of parts of the structure
· Tuning screw
Our valves are produced in two versions, with manual pressure adjustment & with factory settings. The threshold of operation of the models of the first type is set independently in the second case the manufacturer installs a protective cover that prevents the reconfiguration of the product.
As a safety relief valve supplier, we use products of proportional action for incompressible media. Lifting the shutter in them occurs evenly. For compressible substances, protective reinforcement of two-position action is produced. This locks the working medium with a sharp rise. Depending on the required height of the spool lift, the product is made of low-lift, medium-lifting, and full-lifting.
