Sporlan 109055 EBFVE-B-C Expansion Valve

The Sporlan 109055 EBFVE-B-C Expansion Valve is a high-performance balanced port TXV designed for small-capacity commercial refrigeration and air conditioning systems. This model features a 3/8" ODF inlet and 1/2" ODF outlet with extended copper connections, allowing for direct silver soldering into the line without disassembling the valve. The balanced port design is critical for maintaining stable superheat control across widely varying head pressures and evaporator loads, preventing hunting and ensuring precise refrigerant metering between 1.75 to 3 tons capacity.

Utilizing a "C" thermostatic charge, this valve is calibrated for medium temperature refrigeration applications (operating between +50°F and -10°F). It includes an external equalizer (1/4" ODF) to compensate for pressure drops across the evaporator and a 30-inch capillary tube for flexible bulb placement. The brass bar body construction and stainless steel diaphragm provide the durability required for long-term field service in R-22, R-407A, and R-407C systems.

• Precise Superheat Control: The balanced port construction eliminates the influence of inlet pressure fluctuations on valve performance.
• Field Serviceability: Accessible internal components and a 100 mesh insert strainer protect the seat and pin from system contaminants.
• Reliable Construction: Features a knife-edge joint and stainless steel power element for superior leak resistance.
• Optimized Metering: Designed specifically for R-407C and R-22 retrofits where maintaining accurate evaporator feed is essential.

• Can this valve be used for low-temp applications? This specific model uses a Type C charge intended for medium temperature; for low-temp (below -10°F), a Type Z charge would be required.
• What is the purpose of the 1/4" external equalizer? It allows the valve to sense actual evaporator outlet pressure, which is necessary for systems with high pressure-drop distributors.
• Is the superheat adjustable on the 109055? Yes, the EBF series features an external adjustment screw to fine-tune operating superheat based on specific system requirements.
