Karl Dungs High Gas Pressure Switch GMH-A4-4-8 266930

The Dungs 266930 GMH-A4-4-8 Gas Pressure Switch is an adjustable pressure switch designed for automatic gas equipment controls. Part of the GAO, GMH, and GML A4 series, these switches are adaptable to changes in medium pressure relative to the set point, facilitating circuit making or breaking.

They are recommended for industrial and commercial heating applications with 1/4″ NPT pipe connections, suitable for a range of gasses including natural gas, propane, butane, air, and inert gasses. The set point can be easily adjusted in the field using an integrated scale, with a test nipple provided for set point verification.
