More Information about Relief Valves and Safety Valves
Relief valves are used to limit the pressure within a compressed air system.
Pre-set relief valves are often called safety valves and are used on pneumatic components to avoid excessive pressure build-up.
Air tanks such as compressor receiver tanks and other tanks with a maximum rated pressure use an OSHA-rated relief valve.
Adjustable relief valves are often used as control elements in compressed air systems.
Hydraulic relief valves are used extensively in hydraulic systems. They are used to control the oil pressure in much the same way that a regulator does in a compressed air system.
Applications that use relief valves include compressor receiver tanks, pressure vessels, steam turbine kettles, and other pressurized equipment.
