The polymer sensor is designed for fast response in duct environments

Rugged Construction: Encased in a NEMA 1 enclosure made of zinc-coated steel to protect internals from dust and accidental contact

or overheating due to poor ventilation around the heat exchanger

The low internal leakage rate and visible position indicator ensure long-term operational accuracy in demanding commercial and residential HVACR environments

Trane VAL8683 Valve 323080-701 The polymer sensor is designedThe Trane VAL8683 is a high precision thermostatic expansion valve (TXV) designed specifically for R22 refrigerant systems with a 3 ton nominal capacity. Engineered for field replacements and OEM repairs, this valve features a 3 8" inlet and a 1 2" outlet ODF connection, ensuring a secure fit in the liquid line. As an externally equalized component, the VAL8683 valve excels at maintaining precise superheat levels across varying load conditions,
