Description
The Aaon P12440 Hot Gas Bypass Valve is used to regulate discharge gas flow by redirecting a portion of hot refrigerant to maintain evaporator pressure and prevent coil freezing in HVAC systems. It supports system stability during low load conditions by allowing controlled bypass from the discharge line to the suction side. It works through an internal pressure-responsive mechanism that modulates valve opening based on system conditions. Positioned within refrigerant piping it interfaces with compressors and evaporators to manage pressure balance and support consistent system operation.
