The switching mechanism responds to differential pressure which acts between the two pressure chambers. It switches an electric circuit on, off or over when the set reference value is exceeded or undershot. MV – 1 bar, one-stage N. The test nipple is integrated in metal housings as standard.
AV – 6 bar, one-stage N. SV – mbar N. Pressure switch as per EN for burners. Dkngs pressure switch operates without auxiliary power. HFSV – butterfly valve N. AV – 6 bar, one-stage N.

Single-acting pressure switch in the low pressure range. LGV – mbar N. The installation position can change significantly the switching pressure. LGW A4 can be used as differential q4 switches for air and as an over-pressure switch for gas.
Accessories Manuals Datasheets Certificates. Free of non-ferrous metals, suitable for gases up to max. LGW A4 Y are designed for gas and have a yellow adjustment knob.

The specified pressure setpoint operating point is set at a setting wheel using a scale. The installation position can change the switching pressure with up to 0. 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 reacts to overpressure and closes, opens or switches over a current circuit when the specified pressure setpoint is 550 or undershot. Suitable for closing, opening or switching over a current circuit when the actual pressure value deviates from the specified pressure setpoint.

GW A4 acts via a rubber diaphragm against the force of the setting spring on the micro-switch. 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.
VR – mbar Fungs.

The differential pressure acts via the diaphragm against the force of the setting spring on the microswitch. SV – mbar N.
LGV – mbar N. 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. The switching mechanism responds to vacuum which switches an electric circuit on, off or over when the set value is exceeded or undershot.
Single-acting pressure switch in the overpressure range. ZR – two-stage, N.
