The Robertshaw K-78155 S-53 Solenoid Water Valve is a control component that regulates the flow of water in the HVAC system by opening and closing the valve through an electrically operated plunger in response to control signals. It is installed in place of normal piping and is turned on when the system controller makes the solenoid hot, and water only flows when needed to heat, cool, or to control condensate. This valve is installed in boilers, chilled water systems, or auxiliary water circuits, and assists to control the fluid, as well as to provide the correct operation of the system.
