The Sporlan 130797 SVE-8-C is a high-performance 8-ton thermostatic expansion valve engineered for precision refrigerant flow control in R-22 air conditioning and commercial refrigeration systems. Built with a heavy-duty brass bar stock body, this Type S expansion valve features 5/8" x 7/8" ODF solder connections and a balanced port design that maintains stable superheat control across varying head pressures and load conditions. The externally equalized configuration ensures maximum evaporator efficiency by compensating for pressure drops, while the C type thermostatic charge is specifically calibrated for medium-temperature applications ranging from +50°F to -10°F. For the veteran technician, the SVE-8-C offers field-proven reliability with a replaceable power element and an externally adjustable superheat screw, allowing for fine-tuning on-site. The valve is equipped with a permanent 12-mesh inlet strainer to protect the internal orifice from debris, ensuring long-term system integrity. Whether you are performing a TXV replacement on an older R22 chiller or maintaining a large-scale commercial rooftop unit, the Sporlan SVE series provides the durability and consistent seat alignment required for critical HVACR infrastructure. Key Benefits Precise Superheat Control: The balanced port design prevents inlet pressure fluctuations from affecting the pin position, ensuring steady performance. Field Serviceability: Features a replaceable thermostatic element and accessible internal parts for easy cleaning and inspection without removing the valve body. Robust Construction: A brass bar stock body and silver-soldered connections provide high strength and leak-proof reliability under high-pressure conditions. Optimized Charging: The Type C charge minimizes hunting and protects the compressor by maintaining consistent superheat at the evaporator outlet. System Protection: Includes a stainless steel pushrod and a permanent inlet strainer to prevent particulates from compromising the valve seat. Common Questions Can the SVE-8-C be used with R-407C systems? Yes, because R-407C has similar pressure-temperature characteristics to R-22, this valve is often utilized in R-407C retrofits, though superheat should be verified and adjusted during commissioning. What is the purpose of the external equalizer on this 8-ton valve? The external equalizer is critical for 8-ton systems to accurately sense the pressure at the evaporator outlet, compensating for the pressure drop across the distributor and evaporator coils to prevent starving or flooding. Is the power element replaceable on the 130797? Yes, the Sporlan SVE series uses a field-replaceable thermostatic element (Element size 83), allowing you to swap the head without de-brazing the entire valve from the liquid line.
