Safety valves and instrumentation
TÜV safety valves for low pressure
This range covers 144 versions of factory set, sealed TÜV safety valves for gases in the lower pressure range. The set pressure is fixed at the works and spans 0.90 bar to 8.50 bar, with steps such as 2.50 bar, 3.00 bar, 4.00 bar, 4.50 bar and 5.00 bar.
Connection threads run from G 1/2" (DN 13) through G 3/4" (DN 19) and G 1-1/4" (DN 23) up to G 1-1/2" (DN 30). Depending on nominal size and set pressure, the discharge capacity lies between 35.2 m³/h and 2860 m³/h. Seal materials available are FKM and EPDM.

Buying guide
How to choose TÜV safety valves for low pressure
What matters when choosing: properties, comparison and typical applications.
Technical data
Applications
Typical installation points are compressed air networks and compressor stations, pressure vessels and air receivers, plus distribution lines downstream of pressure regulators where the system pressure stays below 10 bar. Small sizes from DN 13 protect individual machines and control loops, while larger bodies up to DN 30 with a discharge capacity of up to 2860 m³/h protect whole network sections. Besides compressed air the valves suit nitrogen and other non-flammable technical gases; the EPDM variant widens the choice of media compared with the standard FKM seal.
