Product Description

Dungs LGW3A4 OR Differential  Adjust Air Compressor 221590 For Gas Burner Parts High Pressure Control Switch

Product Description

 

Application

Differential pressure monitoring in firing, ventilation and air-conditioning systems. Differential pressure switches:suitable for air, flue and exhaust gases. Pressure switches: suitable for gases of families 1,2,3 and other neutral gaseous media.

Technical description

The differential pressure switch LGW… A4 is an adjustable differential pressure switch as per EN 1854 for automatic burner controls. It is suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value. The reference value (switching point) is adjusted on a setting wheel provided with a scale. The test nipple is integrated in metal housing as standard.

 

 

 

Approvals

EC type test approval as per EC Gas Appliance Directive: LGW…A4 CE-0085 AQ 0673 LGW…A4/2 CE-0085 AQ 0673 EC type test approval as per EC Pressure Equipment Directive: LGW… CE0036 Pressure switch Class "S" as per EN 1854. Approvals in other important gasconsuming countries.

 

Functional description

Differential pressure switch in pressure and vacuum ranges. The differential pressure acts via the
diaphragm against the force of the setting spring on the microswitch. The pressure switch operates without any auxiliary power.
Differential pressure switch LGW…A4

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.

 

Overpressure switch LGW…A4 Pressure connection G 1/4

Single-acting pressure switch in the overpressure range. 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 pressure connection G 1/8
may not be closed.

 

Vacuum switch LGW…A4

Pressure connection G 1/8 Single-acting pressure switch in the low pressure range. The switching mechanism responds to vacuum which switches an electric circuit on, off or over when the set reference value is exceeded or undershot. The pressure connection G 1/4 may not be closed.
