The switching mechanism responds to vacuum which switches an electric circuit on, off or over when the set value is exceeded or undershot. It is suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value.

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. Pressure switch as per EN for burners. The differential pressure acts via the diaphragm against the force of the setting spring on the microswitch.

Dungs LGW50 A4 2.5-50 Differential Pressure Switch

Suitable for dunggs of families 1, 2, 3 and other neutral gaseous media, as well as air, flue gases and combustion products. HSAV – semi-automatic N.

The installation position can change the switching pressure with up to 0. Detailed pictures for available models move the mouse over them to zoom: The test nipple is a44 in metal housings as standard. Suitable for closing, opening or switching over a current circuit when the actual pressure value deviates from the specified pressure setpoint. The pressure switch operates without auxiliary power. LV-D – air valve N.

AV – 6 bar, one-stage N. The switching mechanism responds to differential pressure which acts between the two pressure chambers. MV aa4 1 bar, one-stage N. HFSV – butterfly valve N. Single-acting pressure switch in the overpressure range.

LV-D – air valve N.

LGW A4 Y are designed for gas and have a yellow adjustment knob. The installation position can change significantly the switching pressure.

MV – 1 bar, one-stage N. The switching mechanism reacts to overpressure and closes, opens or switches over a current circuit when the specified pressure setpoint is overshot or undershot.
