Description
The Kromschroder 84447300 Gas Pressure Switch 0.4–4″ WC is a monitoring designed to detect and respond to changes in gas or air pressure within combustion and heating equipment. It operates using a diaphragm mechanism that activates an internal switch when the set pressure threshold is reached, allowing system control or shutdown. Commonly installed in burners, boilers, and gas train assemblies, it helps regulate safe operating conditions. In HVAC systems, this pressure switch acts as a safety and control component, ensuring proper pressure levels are maintained for stable and efficient operation.
