Description
The Trane VAL7241 Thermostatic Expansion Valve (TXV) with a 30″ capillary is a refrigerant metering part, an essential component used to regulate the flow into the evaporator coil of HVAC systems sized for approximately 4 tons of cooling capacity. It uses a temperature‑sensing bulb and internal pressure‑balanced mechanism connected by a capillary tube to modulate refrigerant flow based on evaporator load, supporting maintaining proper superheat across varying operating conditions. Mounted in the liquid line ahead of the evaporator coil, this precisely meters refrigerant into the system.
