Description
The Bosch HVAC 8733908302 Check Expansion Valve Kit R410A is a flow control assembly used for high efficiency residential heat pumps and air conditioning systems in HVAC systems. It regulates the volume of liquid refrigerant entering the evaporator coil by responding to temperature, and pressure changes. It is typically used at the inlet of the indoor coil to facilitate the phase change required for heat absorption. It maintains a constant superheat level. It prevents liquid refrigerant from returning to the compressor while optimizing thermal exchange. It ensures the system operates at high seasonal energy efficiency ratios, during varying cooling loads.
