Application for gas regulator with solenoid valve VAD Constant pressure control

The pressure regulator with gas solenoid valve VAD maintains the set gas outlet pressure pG constant when subject to differing flow rates. If a second gas solenoid valve is used upstream of the VAD, this complies with the requirements of EN 746-2 for two Class A gas solenoid valves connected in series.
Application for gas regulator with solenoid valve VAD Constant pressure control with two gas solenoid valves

The pressure regulator with gas solenoid valve VAD maintains the set gas outlet pressure pG constant when subject to differing flow rates.
Application for gas regulator with solenoid valve VAD Constant pressure control with max. pressure switch

In this example, the minimum inlet pressure pe and the maximum outlet pressure pG are monitored with the pressure switches DG..VCT. The simple attachment of the pressure switch module makes installation easier.
Application for gas regulator with solenoid valve VAD >Constant pressure control with noncontrolled pilot gas outlet

In this application, the pilot burner is supplied with a high inlet pressure via the pilot gas outlet. The simple attachment of the bypass valve module makes installation easier. The minimum inlet pressure pe and the maximum outlet pressure pG are monitored with the pressure switches DG..VCT.
