Sporlan 108908 SBFVE-A-C Expansion Valve

The Sporlan 108908 SBFVE-A-C is a high-performance balanced port thermostatic expansion valve engineered for precision refrigerant flow control in systems utilizing R-22. This small brass bar body valve is specifically designed for commercial refrigeration and air conditioning applications, offering a nominal capacity range from 3/4 to 1-1/2 tons. Its balanced port design is critical for maintaining stable superheat across a wide range of operating conditions, ensuring the pin and port remain perfectly aligned regardless of varying pressure drops across the valve.

Built with 3/8 x 1/2 ODF solder connections, this externally equalized TXV features a "C" thermostatic charge, making it ideal for medium temperature refrigeration and residential cooling. The 108908 includes a 60-inch capillary tube and a 100-mesh removable strainer that can be serviced without unsoldering the valve from the system. As the direct replacement for SBFVE-A-C, this unit facilitates a seamless fit-up for field technicians looking to restore system efficiency with a rugged stainless steel diaphragm and adjustable superheat configuration.

• Balanced Port Construction: Eliminates the influence of varying liquid pressures, preventing hunting and ensuring stable evaporator performance.
• Enhanced System Resilience: Features a durable machined brass body and stainless steel internal parts for long-term corrosion resistance.
• Field Serviceability: Equipped with a replaceable power element and a removable 100-mesh strainer for easy maintenance and cleaning.
• Precision Metering: The externally equalized 1/4" ODF line compensates for pressure drops through the evaporator, maximizing coil surface utilization.

• Is the superheat on the 108908 adjustable? Yes, this valve is designed with an externally adjustable superheat screw to fine-tune system performance.
• Can I use this valve with R-407C? While optimized for R-22, the SBFVE series is often compatible with R-407C due to similar pressure-temperature relationships, though a charge check is recommended.
• What is the purpose of the "C" charge designated in SBFVE-A-C? The "C" charge is a medium temperature charge intended for applications where the evaporator temperature remains above -10°F.
