- Capacity: 6½ Ton
- Maximum Operating Pressure (MOP): 667 PSI
- Inlet Connection: 1/2″ ODF (straight body)
- Outlet Connection: 5/8″ ODF (straight body)
- Capillary Tube Length: 60 inches for flexible bulb placement
- Equalization Type: Externally equalized for accurate superheat control in longer or complex evaporator circuits
- Orifice: Number 6 orifice for optimized flow characteristics
- Includes bulb strap for secure thermal bulb mounting
- Valve Type: TGEL 10 series
Why External Equalization?
External equalization connects the valve’s diaphragm reference port to the evaporator outlet rather than the valve outlet. This design compensates for pressure drop across the evaporator, providing more accurate superheat control in systems with distributor nozzles or multi-circuit evaporators — a critical advantage in larger-tonnage R410A systems.
Application
- Commercial and large residential air conditioning systems
- R410A split systems and package units
- Multi-circuit evaporator coil applications
- Systems requiring precise superheat regulation at high operating pressures
