Sporlan 130447 SVE-3-C Expansion Valve

The Sporlan 130447 SVE-3-C Expansion Valve is a rugged, externally equalized thermostatic expansion valve (TXV) engineered for field service in R22 systems. Designed for a 3-ton nominal capacity, this Type S valve features 1/2" x 5/8" ODF solder connections and a "C" charge, making it the preferred choice for medium-temperature refrigeration and residential air conditioning applications. The external equalizer design is critical for maintaining precise superheat control in systems with high pressure drops across the evaporator, ensuring the coil remains fully active without liquid slugging the compressor.

Built with a large flat diaphragm and silver-soldered joints, the Sporlan SVE-3-C offers exceptional durability and leak protection. The field-replaceable thermostatic element allows for fast troubleshooting and repair without breaking the refrigerant lines. As a standard in the HVACR industry, this R22 expansion valve provides consistent pin and port alignment to minimize hunting and optimize refrigerant flow under varying load conditions. For technicians, the 130447 model ensures a reliable mechanical interface and precise subcooling management for legacy equipment maintenance.

• Precise Superheat Control: The external equalizer balances pressure drops to maximize evaporator efficiency.
• Field Serviceability: Features a replaceable thermostatic element for simplified maintenance and reduced downtime.
• Durable Construction: High-strength silver-soldered connections and a stainless steel diaphragm ensure a leak-proof seal.
• Optimized Flow: Designed specifically for 3-ton R22 systems to provide consistent performance across varying ambient temperatures.
• Corrosion Resistance: Internal pin and port materials are selected to resist erosion and common system contaminants.

Is the superheat adjustable on this valve?
Yes, the Sporlan SVE-3-C features an adjustable superheat design, allowing technicians to fine-tune system performance during installation or service.

What is the difference between an internal and external equalizer on this model?
This model uses an external equalizer, which is necessary for 3-ton systems where the pressure drop across the evaporator is significant. It ensures the valve senses the actual outlet pressure of the evaporator coil.

Can this TXV be used with refrigerants other than R22?
The 130447 is specifically charged and calibrated for R22. While some Sporlan valves are compatible with multiple refrigerants, the "C" charge in this SVE series is optimized for R22 medium-temperature applications.
