Sporlan 108640 SBFV-AA-C Expansion Valve

The Sporlan 108640 SBFV-AA-C is a precision-engineered thermostatic expansion valve (TXV) designed for high-performance flow regulation in R22 refrigeration and air conditioning systems. Featuring a unique balanced port design, this valve compensates for varying head pressures and shifting evaporator loads, ensuring consistent superheat control across a capacity range of 1/2 to 2/3 ton. Built with a durable brass bar stock body, the SBF series includes an internal equalizer and 3/4" ODF sweat connections for high-integrity, leak-proof joints. The Sporlan "C" thermostatic charge is specifically optimized for commercial refrigeration applications, preventing liquid slugging while maintaining maximum evaporator efficiency. This TXV also includes a 100-mesh removable strainer, allowing technicians to service internal components without de-soldering the valve from the liquid line, making it a reliable solution for small-capacity chillers, food service units, and residential split systems requiring R22 refrigerant compatibility.

• Stable Superheat Control: The balanced port construction prevents pressure drops from influencing valve operation, providing stability in systems with widely varying operating conditions.
• Simplified Maintenance: Equipped with a 100-mesh removable strainer that can be cleaned or replaced while the valve body remains installed.
• Reliable Sealing: Features a knife-edge to metal joint and silver-soldered connections to ensure leak-free performance in demanding HVACR environments.
• Application Versatility: Ideal for 1/2 ton to 2/3 ton R22 systems, including refrigerated cases, reach-in coolers, and small-tonnage air conditioners.

Can I use this valve in a system with an external equalizer?
No, the Sporlan 108640 SBFV-AA-C is internally equalized. If your system has a significant pressure drop across the evaporator, you should use the SBFVE series, which includes an external equalizer connection.

What does the 'C' charge signify for this TXV?
The 'C' charge indicates a commercial refrigeration thermostatic element. It is designed to provide optimal response times and control for medium and low-temperature applications using refrigerant R22.

How do I adjust the superheat on this model?
This SBF series valve features an adjustable superheat design. Technicians can fine-tune the setting by removing the bottom cap and rotating the adjustment stem to match the specific load requirements of the evaporator.
