Description
The Sporlan Controls 124721 Thermostatic Expansion Valve (TXV) is a refrigerant flow control valve that regulates liquid refrigerant entering the evaporator by sensing temperature and pressure changes at the outlet to maintain stable superheat levels. It is rated for 35-ton capacity and calibrated for R404A refrigerant, using 1-1/8″ inlet and 1-3/8″ outlet connections for secure brazed line integration within HVAC systems. It is positioned at the evaporator inlet section where it meters refrigerant according to cooling load demand. This supports steady evaporator operation, prevents compressor damage from liquid floodback, and maintains consistent cooling performance under varying system conditions.
