Safety valves
Safety valves serve for pressure relief in order to protect a pressurised system such as pressure vessels or pipelines against inadmissibly high pressures. They thus prevent damage to the pressurised system. Safety or blow-off valves release gases or vapours into the atmosphere or into collectors.
Safety Valves SV805/805A
Blow-off of vapours and gases from vessels, pipelines and other plant components from 0.5 to 45.0 bar with the spring-loaded, direct-acting safety valve. With the optional adapter for connection of a blow-off line, the discharged gases can be collected and do not escape into the atmosphere.
The safety valves SV805 or SV805A with adapter allow blow-off volumes from 15.7 to 665.3 m3/h with opening pressures up to 45 bar that can be individually set at the factory. The adapter serves for connection of a blow-off line. Different gasket materials are available, depending on the gas type. The safety valve is particularly compact for simple installation. Additional function test with lift function possible with the SV805A.
