The Sporlan 109035 EBFVE-A-C TXV is a precision-engineered thermostatic expansion valve (TXV) specifically designed for systems utilizing R-22 refrigerant. Built with a robust brass bar body, this balanced port TXV is engineered to maintain consistent evaporator superheat across widely varying head pressures and load conditions, making it an essential component for both commercial refrigeration and precise air conditioning applications. It features 3/8 x 1/2 ODF solder connections and an external equalizer to compensate for pressure drops through the evaporator coil, ensuring maximum coil efficiency. The unit includes a 30-inch capillary tube and a Type C thermostatic charge, optimized for medium-to-low temperature ranges. With a nominal capacity rated between 0.75 and 1.5 tons, the EBFVE-A-C offers the flexibility required for smaller refrigeration circuits where tight modulation is critical. The design incorporates a 100 mesh insert strainer and a field-replaceable thermostatic power element, allowing for straightforward maintenance and long-term serviceability in the field. Key Benefits for Technicians Balanced Port Design: Maintains stable superheat control even during significant fluctuations in ambient temperature or system load. Internal 100 Mesh Strainer: Protects the valve seat from contaminants to prevent refrigerant flow restrictions and TXV hunting. Extended ODF Connections: Facilitates high-strength silver soldered joints without the risk of overheating the valve’s internal seals during installation. Externally Adjustable: Allows for fine-tuning of superheat settings to match specific evaporator requirements for optimal heat transfer. Replaceable Power Element: Simplifies field service by allowing the replacement of the diaphragm and sensing bulb without removing the valve body from the line. Common Questions Is the Sporlan EBFVE-A-C compatible with R-407C? While originally designed for R-22, this valve is often utilized in R-407C retrofit applications; however, technicians must verify thermal charge compatibility and adjust superheat to account for the pressure-temperature glide of the HFC blend. What causes high superheat in a Sporlan TXV system? High superheat typically indicates a restricted flow. Check the 100 mesh insert strainer for debris, ensure the sensing bulb is securely mounted at the 4 or 8 o'clock position on the suction line, and verify that the external equalizer line is not blocked. Can this valve be used in bi-directional heat pump applications? The EBF series is primarily a straight-through design. For heat pump applications requiring reverse flow, an internal check valve model or an external bypass check valve must be integrated into the refrigerant circuit.
