Safety valves and instrumentation
TÜV angle safety valves for liquids
Angle safety valves for liquids limit the pressure in closed circuits and vessels and discharge as soon as the preset value is exceeded. The range covers 213 versions with connection threads from G 1/2" to G 1-1/2" and nominal sizes from DN 10 to DN 25. Inlet and outlet are arranged at 90 degrees to each other, so the valve can be fitted straight into a pipe corner or onto a vessel socket.
Set pressures are factory set and sealed. Documented values run from 1.0 bar through 2.3 bar, 4.0 bar and 6.6 bar up to 15.0 bar, covering the band from 1 to 16 bar. Besides the standard version, a variant for cooling circuits is available.

How to choose TÜV angle safety valves for liquids
What matters when choosing: properties, comparison and typical applications.
Technical data
Applications
The valves are used in liquid systems such as cooling and refrigeration circuits, heating and hot water installations, pump circuits, pressure vessels and storage tanks. The cooling circuit version starts at 1.0 bar and therefore also suits plants with low operating pressure, while valves rated up to 15.0 bar are placed on pump discharge sides and heat transfer circuits. Larger nominal sizes up to DN 25 are chosen where a controller failure or thermal expansion requires a correspondingly high flow to be released. Installation is at the highest point of the protected section, with free drainage into a collecting line.
