Safety Valves

Safety valves limit pressure in pneumatic and fluid systems by opening automatically once a set response pressure is exceeded and discharging medium. The range covers more than 4,000 items, from mini designs in DN 3 up to nominal widths of DN 48, including adjustable, TÜV- and ASME-certified variants.

The series cover response pressures from below 1 bar to 60 bar, for example the SVM mini safety valves in stainless steel 1.4305 with G 1/8" and G 1/4" connections. Corner, overflow and pressure relief valves are also available for varying mounting positions and flow requirements.

Buying guide

How to choose Safety Valves

What matters when choosing: properties, comparison and typical applications.

Typical Applications

Safety valves protect pressure vessels, compressors, piping systems and aggregates against inadmissible overpressure. Stainless steel mini designs suit measuring and control lines as well as applications with high purity or corrosion requirements, while TÜV- and ASME-certified series are intended for monitored installations.

Selection Criteria

Response pressure the pressure at which the valve opens, ranging from below 1 bar to 60 bar in this range.
Nominal width determines discharge capacity, here from DN 3 to DN 48.
Material stainless steel 1.4305 for corrosive or clean media, brass for standard applications.
Approval TÜV or TÜV/ASME for pressure equipment subject to inspection.
Design straight, corner or overflow type depending on mounting position.
