Emerson Alco 009955 Expansion Valve

The Emerson Alco 009955 (Model: HFE 1/2 FC 5FT 1/4 x 1/2 SAE ANG) is a high-performance balanced port thermal expansion valve engineered for precise refrigerant metering in medium-temperature applications. Designed for a 1/2 ton R12 capacity, this externally equalized TXV ensures stable superheat control even under varying head pressures or fluctuating load conditions. The stainless steel power assembly provides superior resistance to corrosion, ensuring long-term reliability in demanding refrigeration and HVACR systems.

Featuring an angle body configuration with 1/4" x 1/2" SAE flare connections, this valve is optimized for straightforward installation and field serviceability. The 5-foot capillary tube allows for flexible remote bulb placement, which is essential for accurate temperature sensing at the evaporator outlet. As a veteran-grade refrigerant flow control component, it is widely utilized for commercial refrigeration equipment, small-scale chillers, and specialized environmental chambers where R12 charge requirements and medium-temperature precision are critical.

• Balanced Port Design: Minimizes the effects of fluctuating head pressure, ensuring consistent performance across all operating ranges.
• Corrosion Resistance: Equipped with a stainless steel power assembly to prevent valve failure in high-moisture environments.
• External Equalization: Compensates for pressure drops across the evaporator, maintaining optimal superheat for peak system efficiency.
• Flexible Mounting: The angle body and 5' capillary tube accommodate tight piping configurations common in refrigeration applications.

• What refrigerant is this valve compatible with? While primarily rated for R-12, this HFE series valve is often used in systems that have been converted to R-134a or other compatible medium-temperature blends, provided capacity and superheat are verified.
• How do I adjust the superheat on this model? The 009955 features an external adjustment stem; turn clockwise to increase superheat and counter-clockwise to decrease it.
• Where should the external equalizer be connected? For proper operation, the 1/4" SAE equalizer line must be tapped into the suction line just downstream of the sensing bulb.
