Spence Engineering D320 Pressure Pilot CI Type-D 3–20 PSI Spring Range

The Spence Engineering D320 Pressure Pilot CI Type-D is an accuracy-controlled component that needs to work under pressure between 3-20 PSI. This system is applied to control pressure in commercial HVAC systems that are stable when operating within different conditions. It is mostly fitted in boilers, burners, and other gas control systems where it is used to provide the necessary monitoring and control of gas flow. The spring mechanism ensures constant pressure on the part of the pilot which supports the overall system efficiency and reliability of the system.
