Sporlan 044439-01 TXV Valve

The Sporlan 044439-01, technically cataloged as the HCAE-3-VX100H, is a balanced port thermostatic expansion valve (TXV) engineered specifically for high-demand residential and light commercial air conditioning and heat pump systems. This Chatleff connection TXV is optimized for R-22 and R-407C refrigerants, featuring a 3-ton nominal capacity that ensures precise refrigerant metering across varying load conditions. Designed with a stainless steel power element and a balanced port construction, the HCAE series mitigates the effects of high pressure drops, preventing liquid floodback and protecting the compressor from damage during low-load operation. The external equalizer and internal check valve facilitate seamless bi-directional flow, making it a reliable solution for heat pump defrost cycles and varied evaporator temperatures.

Key Benefits for Technicians

• Balanced Port Design: Compensates for fluctuating head pressures and varying evaporator loads to maintain consistent superheat control.
• Chatleff Connections: Provides a standardized, secure fit for simplified field replacement in compatible evaporator coils.
• R-407C & R-22 Compatibility: Versatile application for both legacy R-22 systems and modern R-407C retrofits.
• Internal Check Valve: Standard on the HC series to allow reverse flow in heat pump applications without additional piping.
• Stainless Steel Diaphragm: High-strength power element resistant to corrosion and fatigue for long-term system stability.

Common Questions & Technical Support

• How do I adjust the superheat on this valve? This model features a field-adjustable superheat stem. Rotate clockwise to increase superheat (reduce flow) or counter-clockwise to decrease superheat (increase flow).
• Does this TXV require an external equalizer? Yes, the HCAE-3-VX100H utilizes an external equalizer to accurately sense pressure at the evaporator outlet, ensuring the valve responds to the actual coil pressure drop.
• Can this be used on a 2-ton system? Yes, with a 1.5 to 3-ton operating range, this 3-ton nominal valve is suitable for smaller tonnage applications requiring precise refrigerant regulation.
