The switching mechanism reacts dunvs overpressure and closes, opens or switches over a current circuit when the specified pressure setpoint is overshot or undershot.

The reference value switching point is adjusted on a setting wheel provided with a scale.

It switches an electric circuit on, off or over when the set reference value is exceeded or undershot. 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.

AV – 6 bar, one-stage N. LV-D – air valve N. LGW A4 can be used as differential pressure switches for air and as an over-pressure switch for gas.

LGW A4 Y are designed for gas and have a yellow adjustment knob. The differential pressure acts via the diaphragm against the force of the setting spring on the microswitch. LV-D – air valve N.

Pressure switch as per EN for burners. HFSV – butterfly valve N.

The test nipple is integrated in metal housings as standard. GW A4 acts via a rubber diaphragm against the force of the setting spring on the micro-switch.

VR – mbar N. The installation position can change the switching pressure with up to 0. SV – mbar N. The pressure switch operates without auxiliary power. Free of non-ferrous metals, suitable for gases up to max.

The specified pressure setpoint operating point is set at a setting wheel x4 a scale. Accessories Manuals Datasheets Certificates. Suitable for gases of families 1, 2, 3 and other neutral gaseous media, as well as air, flue gases and combustion products. ZR – two-stage, N. MV – 1 bar, one-stage N.

Pressure switch for applications involving excess pressure. Single-acting pressure switch in the low pressure range. VR – mbar N.

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

ZR – two-stage, N.

HSAV – semi-automatic N. The switching mechanism responds if there is an overpressure which switches on, off or over to an electric circuit if rungs set reference value is exceeded or undershot.
