Carrier EA52PH057 Piston R-407C this pilot operated solenoid valveThe Carrier EA52PH057 Piston is a precision engineered metering device designed for fixed orifice refrigerant control in specific Carrier, Bryant, and Payne residential AC and heat pump systems. With a diameter or bore size of . 057, this component ensures the precise drop in pressure required for efficient liquid to vapor transition in the evaporator coil. Unlike thermostatic expansion valves (TXV), this HVAC orifice piston provides a reliable, cost
