Gas Pressure Switches with Modular Mount

The DUNGS GAO (Automatic Reset) A2 pressure switches are compact pressure switches for DUNGS modular valve train components. 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.The switches incorporate a vent limiter as per UL 353 and limits the escape of gas less than 1.0 CFH of natural gas at 7 PSI if internal switch diaphragm ruptures.

Application

The DUNGS GAO 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 A2 pressure switches are suitable for natural gas, propane, butane, air and other inert gases. Mounts directly to DMV, FRI and Flanges; use adapter (214975) 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 and O-ring included)
