Description
Sporlan Controls 128570 Thermostatic Expansion Valve
The Sporlan Controls 128570 is a thermostatic expansion valve (TXV) engineered for reliable, precise refrigerant metering in commercial and residential refrigeration and air conditioning systems. Featuring a 5/8″ ODF liquid line inlet and a 1-1/8″ ODF suction line outlet, this valve is designed for larger-capacity systems where accurate superheat control is critical to system efficiency and compressor protection. The 5-foot capillary tube provides flexible bulb placement, allowing technicians to position the sensing bulb at the optimal location on the suction line for accurate temperature sensing and responsive valve operation.
