Pressure switch GW A4 Dungs for gas, air, flue 05, combustion products These pressure switches GW A4 are designed for monitoring in burner control systems. Detailed pictures for available models move the mouse over them to zoom: The switching mechanism responds if there is an overpressure which switches on, off or over to an electric circuit if the set reference value is exceeded or undershot.
LGW A4 can be used as differential pressure switches for air and as an over-pressure switch for gas. ZR – two-stage, N.
Suitable for closing, opening or switching over a current circuit when the actual pressure value deviates from the specified pressure setpoint.

VR – mbar N. GW A4 acts via a rubber diaphragm against the force of the setting spring on the micro-switch.
The reference value switching point is adjusted on a setting wheel provided with a scale. LV-D – air valve N.

Accessories Manuals Datasheets Certificates. They are used as differential pressure switches for air, flue and exhaust gases, and as simple pressure switches they are suitable for gases of families 1, 2, 3 and other neutral gaseous media.
The test nipple is integrated in metal housings as standard. MV – 1 bar, one-stage N. Pressure switch for applications involving excess pressure. ZR – two-stage, N. LV-D – air valve N. SV – mbar N. MV – 1 bar, one-stage N. Single-acting pressure switch in the overpressure range.
Accessories Manuals Datasheets Certificates. It switches an electric circuit on, off or over when the set reference value is exceeded or undershot.
Pressure switch as per EN for burners. HSAV – semi-automatic N. The installation position can change significantly the switching pressure. VR – mbar N. HFSV – butterfly valve N. z4
GWA4, GWA4/2: Gas and air pressure switch – DUNGS® Combustion Controls
The switching mechanism reacts to overpressure and closes, opens or switches over a current circuit when the specified pressure setpoint is overshot or undershot. The pressure switch operates without auxiliary power. HFSV – butterfly valve N. Free of non-ferrous metals, suitable for gases up to max. LGV – mbar N. It is suitable for switching a circuit on, off or over on changes s4 actual pressure value relative to the set reference value. The switching mechanism responds to ggw which switches an electric circuit on, off or over when the set value is exceeded or undershot.
SV – mbar N.
