A safety valve is a type of pipeline fittings, an automatic machine designed to protect closed channel (pipeline) systems, devices, machines, and containers installed in them from damage by excessively high or low (vacuum) pressure. Protection of a closed thermodynamic system by a Pressure safety valve is carried out by dumping (during vacuuming - suction) a part of the working medium.

Unlike irrevocably collapsing safety (bursting) diaphragms, the automatic mechanism of the safety valve ensures the termination of the discharge of the working medium when the emergency pressure in the circuit normalizes to a safe (working) value. Thus, operable safety valves simultaneously retain:

Any safety valve has a simple principle of operation. Initially, the shut-off element is pressed against the saddle by a spring. Under the influence of increasing pressure, the spring is compressed and moves the shut-off element away from the saddle. The formed lumen rushes the excess mass of the working environment.

Pressure Safety Valve Manufacturerdesigned it to release excess liquid, vapour, or gaseous media from a high-pressure system automatically! It also happens with an excessive increase in pressure in it into a low-pressure system or the atmosphere & ensures the safe operation of installations and the prevention of accidents. These valves refer to as safety valves, which are of two types: reusable and disposable (bursting devices - membranes or caps).

The pressure reducing valve is an essential accessory of the pneumatic regulating valve. Its main function is to reduce the pressure of the air source and stabilize it to a fixed value, so that the regulating valve can obtain stable air source power for regulating control.

The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure.

The main parameter of the air compressor safety valve is the displacement, which is determined by the diameter of the valve seat and the opening height of the valve disc.
