Sporlan 100431 BFV-AAA-C 2X4 SAE Expansion Valve

Integrate the Sporlan 100431 BFV-AAA-C into your low-capacity R22 systems to ensure precise refrigerant flow regulation and consistent superheat control. This balanced port thermostatic expansion valve is engineered for applications ranging from 1/8 to 1/3 tons, making it ideal for residential AC units and small-scale commercial refrigeration. The 2x4 SAE flare connections provide a secure, leak-free mechanical joint, while the 30-inch capillary tube offers flexible bulb placement for accurate temperature sensing. Designed to handle widely varying operating conditions, the Sporlan BFV series utilizes a brass bar stock body and a knife-edge joint for maximum durability under high-pressure cycles. By maintaining accurate superheat at the evaporator outlet, this R22 expansion valve prevents liquid slugging and optimizes compressor longevity. Contractors rely on the BFV-AAA-C for its internally equalized design and 100-mesh removable inlet strainer, which protects the metering orifice from debris and contaminants common in older R22 systems.

Key Benefits:

• Balanced Port Design: Compensates for variations in head pressure, ensuring stable evaporator feeding during changing load conditions.
• Precise Capacity Control: Rated for 1/8 thru 1/3 ton, providing fine-tuned metering for small-tonnage equipment.
• Durable Construction: Features a rugged brass body and stainless steel diaphragm for long-term reliability in demanding HVACR environments.
• Field Serviceable: The removable 100-mesh strainer allows for easy cleaning without breaking the refrigeration lines.
• Optimized for R22: Specifically calibrated for R22 refrigerant systems with a standard "C" thermostatic charge.

Common Questions:

• What is the connection size for this valve? The Sporlan 100431 features a 3/8" SAE flare inlet and a 1/2" SAE flare outlet (often referred to as 2x4 SAE in technical sizing).
• Is this valve internally or externally equalized? This model is internally equalized, making it suitable for systems without significant pressure drops across the evaporator.
• Can this be used for R407C retrofits? While the physical connections may match, this valve is factory-charged for R22 systems; consult technical specifications to ensure the pressure-temperature curve aligns with your specific retrofit requirements.
