The Dungs G..-A2 Gas Pressure Switches are compact pressure switches for a modular valve train. These G..-A2 gas pressure switch types are: GAO (Automatic Reset), GMH (High Manual Reset), and GML (Low ManualReset).
G..-A2 pressure switches are suitable for making and/or breaking a circuit when the medium pressure changes relative to the set point. The set point can be set in the field by an adjustable dial with an integrated scale.
Dungs GAO, GMH, and GML A2 pressure switches are recommended for industrial and commercial heating applications with Dungs DMV dual modular valves and Dungs FRI modular pressure regulators.
The GAO, GMH, and GML A2 pressure switches are suitable for natural gas, propane, butane, air and other inert gases.
Mounts directly to DMV, FRI and Flanges; use adapter (273777) for DMV downstream [Port 3] Calibrated for vertical mounting, set point may change by 0.2” W.C. when mounted otherwise; Screw terminals with 1/2 NPT Conduit connection; Neon light included. Mounting kit (2 screws andO-ring included).
