Description
The Amana-Goodman B1789876 0.76 Flow Check Piston regulates refrigerant through a fixed point to maintain balanced pressure between high and low sides ensuring controlled metering during the cooling cycle. It operates by using a precision piston that shifts refrigerant passage based on pressure differential stabilizing flow within the coil circuit. It is positioned inside the expansion assembly and where it aligns with internal seating to direct refrigerant movement accurately. It improves heat exchange consistency reduces flow fluctuation, and maintains steady system operation in HVAC systems such as air conditioners and heat pumps.
