Sporlan Controls 902938 7/8" Head Pressure Control Valve W/Strainer 0-210 PSI

The Sporlan Controls 902938 pressure control valve is utilized in a variety of HVAC equipment, such as chillers, boilers, and air handling units. Specifically, it serves as a pressure controlling valve, sometimes referred to as a thermostatic expansion valve. Its 7/8-inch head and sweat connection make it compatible with a variety of existing systems.  The Sporlan Controls 902938 regulates the flow of refrigerant or water via an HVAC system. It reacts to temperature changes to maintain constant pressure. The valve opens to let more water or refrigerant flow when the temperature rises, which helps with heat absorption. When the temperature drops, the valve tightens, limiting flow and protecting the system from overcooling.
