Parker-Jackes Evans 78032 Coil 120V H-23R

The Parker-Jackes Evans 78032 Coil 120V H-23R is an electromagnetic solenoid component used to control valve operation within refrigeration and air conditioning equipment. It converts electrical energy into a magnetic field that activates compatible solenoid valves, regulating refrigerant flow in components such as liquid line in HVAC systems. It is installed on valve assemblies inside chillers, heat pumps, and air handling systems, where accurate control of refrigerant movement is required for efficient system cycling. As part of the control circuit, it ensures accurate opening and closing of the valve based on thermostat or system signals, maintaining stable cooling or heating performance in commercial connection.
