The Sporlan 108631 SBFV-A-C is a high-performance balanced port expansion valve engineered for precision refrigerant metering in systems with fluctuating head pressures and varying loads. Designed specifically for R22, R407A, and R407C applications, this Type SBF valve features a durable brass bar body with 3/8" x 1/2" ODF solder connections and a 30-inch capillary tube. The balanced port construction ensures stable superheat control by neutralizing the effects of pressure drop across the TXV, preventing erratic hunting during low-load conditions. As a medium temperature C-charge valve with a nominal capacity range of 3/4 to 1-1/2 tons, it utilizes a replaceable thermostatic element (Element Size 43) and an internally equalized design to streamline installation in commercial refrigeration, healthcare cooling, and food retail units. The integrated 100-mesh removable strainer allows for internal cleaning without de-soldering, maintaining high system reliability and protecting the stainless steel pin and port from debris.

Key Benefits for the Contractor:
  • Balanced Port Design: Maintains precise pin and port alignment to eliminate operation interference from inlet pressure changes.
  • Field-Serviceable Construction: Features accessible internal parts and a removable 100-mesh strainer for easy maintenance without removing the valve from the line.
  • Enhanced Compatibility: Optimized for R22 refrigeration systems and compatible with R407A/C alternatives, providing versatile inventory management.
  • Robust Build Quality: Utilizes a stainless steel diaphragm with knife-edge-to-metal joints for a leak-proof, high-strength connection.
  • Adjustable Superheat: Allows for fine-tuning system performance in the field to meet specific evaporator requirements.
Common Questions & Technical Insights:

Is the Sporlan SBFV-A-C internally or externally equalized?
This specific model (108631) is internally equalized. For systems with significant pressure drops across the evaporator or distributor, ensure an internal equalizer is appropriate for your suction line configuration.

Can I use this valve with R407C systems?
Yes, the Sporlan SBFV-A-C is rated for R407C and R407A in addition to R22, making it an excellent choice for retrofits and modern commercial refrigeration applications.

What is the advantage of the "C" thermostatic charge?
The C charge is a liquid-cross charge designed for medium-temperature applications (typically +50°F to -10°F), providing stable control and preventing power element migration in various ambient conditions.
