1.2 Application

 

The UNI Geräte Gas – Solenoid valves 40/55-EVF..NH.Ü.. are used as automatic safety shut-off 
valves for protection, limitation, shut-off and release of gas and air supply at main stops of in front of 
gas burners. e.g. to DIN EN 13611, DIN 3394-1 and DIN EN 16678.. 
 
The valves are suitable for gases of the 1

st

, 2

nd

 and 3

rd

 gas families to G260 and for neutral gases and 

as a variant with material design for aggressive gases such as e.g. biogas, sewage plant gas or dump 
gas to G262. 
 
If used in other cases, the operator must carefully check if construction/design of valve, accessories 
and materials are suitable for the new application. The range of application is subject to the 
responsibility of the plant planner. The service life of the valve is 20 years.
