Stoelting 762443 Serve Freezer Thermostatic Expansion Valve

The Stoelting 762443 Thermostatic Expansion Valve regulates refrigerant flow within a commercial serve freezer system by responding to evaporator temperature changes. It adjusts refrigerant metering by controlling liquid flow into the evaporator coil using bulb feedback and internal spring balance to maintain required phase change conditions inside the circuit while balancing superheat control across operating cycles and ensuring steady refrigerant feed under varying load conditions of the freezer cabinet. It is installed at the expansion point between the liquid line and the evaporator inlet in service freezer refrigeration assembly systems.
