York 024-39397-001 Differential Water Pressure(DWP) Flow Switch 150PSI 24V

The York 024-39397-001 Differential Water Pressure (DWP) Flow Switch is an essential part of the HVAC system, that functions to detect and regulate the water flow in the system for proper functioning. This flow switch operates at 24V, has a pressure range of up to 150 PSI, and is made from materials that include brass or stainless steel to allow it to withstand tough conditions. This flow switch operates based on the variation of the water pressure differential within the HVAC system. It is meant to switch on or off electrical signals depending on certain pressure levels to control the on/off of water flow in the system. Maintaining the water pressure at the specified levels avoids problems such as pump cavitation or having an inefficient water system.
