Gas pressure switches
DG..C monitors the increasing or decreasing positive pressureof natural gas, town gas, LPG, flue gas, biologically producedmethane and air e.g. on a gas control line. If the gas pressureeither exceeds or falls short of a set switching point, an NOcontact or a change-over contact will switch in the pressureswitch. With the DG..VC, the switching point may be adjustedusing a hand wheel. The DG..VC is suitable for heating boilers,for example, which are operated with LPG as well as naturalgas. In the case of the double pressure switch DG../..VC, theminimum and maximum switching point can be set on twohand wheels. Using this function, a system is controlled toprevent gas deficiencies and excess gas pressure. For pressurecontrol it requires only one gas connection. The electricalconnections can be fed in from one direction. For attachmentto gas solenoid valves or pressure regulators from the valVariorange, or to CG combination controls, the DG..C is attached tothe control with the flat sealing lower section.
