The Trane VAL1279E Electronic Expansion Valves, Sporlan SERI-KS is an advanced, electronically operated stepper motor flow control valve designed for precise liquid refrigerant management in commercial air conditioning and refrigeration systems. The “9×11” designation refers to its specific configuration profile, commonly mapped to standard connection sizing (such as 1-1/8″ x 1-3/8″ ODF configurations depending on exact dash sizing requirements). Part of Sporlan’s reputable SERI family, this valve features a built-in sight glass for real-time diagnostics and refrigerant charging.

Key Features & Benefits

• Precise Flow Control: Uses a digital linear actuator and synchronized stepper motor signals for exact linear positioning of the valve piston.
• Built-In Sight Glass: Allows visual confirmation of valve piston movement, moisture levels, and flash gas checks upstream.
• High-Resolution Performance: Features fine resolution steps to yield supreme accuracy in superheat control and flow repeatability.
• Versatile Compatibility: Fully compatible with all common HCFC and HFC refrigerants (including R-410A) and subcritical CO2 ($\text{R-744}$), alongside mineral, polyolester (POE), and alkylbenzene oils.
• Flexible Integration: Interfaces seamlessly with microprocessor-based controllers, including Parker Sporlan superheat controllers and interface boards.
