Safety Valves – Steam Safety Valves
• Safety equipment used in steam heating systems to release excessive pressure and prevent damage to the system.
• Unlike fixed-pressure safety valves, the opening pressure of these valves can be adjusted on-site by the customer, allowing settings between 2 – 12 bar.
SAFETY VALVE
An adjustable steam safety valve is the name given to a valve mechanism that automatically releases gas when a pressurized tank or other system reaches a predetermined temperature or pressure limit. It is important to use safety valves in boilers and tanks to ensure system safety. Safety valves are also used as auxiliary components in heat exchangers and pressurized tanks. The membrane inside the valve is manufactured to be resistant to wear. The opening pressures are fixed, but if desired, the set values can be pre-adjusted at the factory.
They are installed in the system to prevent excessive fluid pressure from damaging the piping, other connected devices, or valves. They operate with a spring-loaded mechanism based on the counter-pressure principle. Different connection diameters are available depending on the boiler capacity and the amount of water in the system. In cases where the valve capacity is insufficient, multiple safety valves can be connected “in series” on the line.
Applications of Adjustable Steam Safety Valves:
-
Water heater systems
-
Heating boiler systems
-
Gas release from tanks
