How the safety valve works
The
safety valve is designed to open and relieve excess pressure or vacuum from vessels or equipment. At the same time, it is designed to close and prevent further release of liquid / gas after normal conditions are restored.
The control safety valve is a safety element designed to protect the container or system under pressure during an overpressure event. An overpressure event refers to any condition that could cause a pressure rise in a vessel or system that exceeds a certain design pressure or maximum allowable working pressure. The safety valve ensures that the supply medium pressure is not exceeded.
If the supply medium pressure rises above the setpoint, the supply medium connects to the valve until the pressure drops below the setpoint.
The safety valve belongs to the group of pressure valves - pressure safety valves.

What is a pressure safety valve
A pressure saftey valve is a pressure relief element that begins to respond when pressure exceeds the maximum allowable operating pressure. Pressure relief valves protect pressurized spaces or pressure vessels (eg boilers and steam generators, pipelines, reactors) against pressure build-up that is unacceptable to pressure equipment or pressure systems. When the set pressure is exceeded, gases, vapors or liquids are discharged into the atmosphere or into the manifolds.
Where pressure relief valves are used
They are used in systems for the needs of:
- chemical industry,
- the gas industry,
- process industries,
- packaging lines in the food industry,
- health,
- the printing and graphic industries,
- other systems operating under pressure.
