Product Overview
Sporlan Controls is a globally recognized leader in refrigeration and HVAC controls, and the 125691 TXV upholds that reputation with robust construction and reliable performance. The valve’s thermostatic sensing element continuously monitors superheat at the evaporator outlet and modulates refrigerant flow to maintain optimal system operation — even under varying load conditions.
With 7/8″ ODF connections on both the inlet and outlet, this valve is well-suited for the larger line sets found in 20-ton commercial installations. The R-410A rating ensures compatibility with modern, environmentally compliant systems that have transitioned away from R-22.
Applications
- Commercial air conditioning systems (20-ton capacity)
- Large split and packaged HVAC systems using R-410A
- Refrigeration systems requiring precise superheat control
- Replacement or upgrade of existing TXV components
