Description
The Dungs Pressure Switches 266930 M/R Gas Pressure Switch monitors gas pressure levels and activates electrical contacts when pressure reaches the adjustable operating range. It operates through an internal diaphragm sensing mechanism that responds to pressure variation between 40-200″ WC, allowing accurate switching control in HVAC systems such as burners, boilers, and gas-fired heating equipment. Built with a 1/4″ NPT connection, it integrates into the gas line and control circuit to supervise pressure conditions during operation. It supports safe gas pressure monitoring, maintain stable combustion control, and contributes to heating system performance.
