DG..C monitors the increasing or decreasing positive pressure of natural gas, town gas, LPG, flue gas, biologically produced methane and air e.g. on a gas control line.

For use with the valVario gas solenoid valves, the DG..C is attached to the valve with the flat sealing lower section.

If the gas pressure either exceeds or falls short of a set switching point, a NO contact or a change-over contact will switch in the pressure switch. The switching point may be adjusted using a hand wheel.

In the case of the double pressure switch DG../.. VC, the minimum and maximum switching point can be set on two hand wheels. Using this function, a system is controlled to prevent gas deficiencies and excess gas pressure. For pressure control it requires only one gas connection. The electrical connections can be fed in from one direction.
