A start capacitor and relay are necessary for single-phase compressors to overcome the head pressure at startup

Technical integration is streamlined via a 1/4" compression coupling gas fitting and screw terminal connections for the integrated flame and ignition electrodes

This cast iron water valve is designed to modulate water flow through a heat exchanger to maintain a specific temperature setpoint between 160°F and 230°F

Its solid core construction prevents attrition

providing critical end-stop feedback or the ability to trigger external equipment like pumps or fan coils
