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 valve AV619
Application
Spring-loaded, direct-acting safety valves for the blow-off of vapours and gases from vessels, pipelines and other plant components from 5 to 500 mbar.
Reliable blow-off with individually adjustable opening pressure
With its different connections, the spring-loaded safety valve AV619 offers blow-off volumes from 2.6 to 90.7 m3/h with opening pressures from 5 to 500 mbar that can be individually set at the factory. Different gasket materials are available, depending on the gas type. Thanks to its compact dimensions, the safety valve offers easy installation.

Safety Valves SV805/805A
Application
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.
Reliable blow-off with individually adjustable opening pressure with blow-off line connection
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.
| Opening pressure: | 0.5 to 45.0 bar |
| Blow-off volumetric flow: | 22.7 to 967 m³/h |
