Engineered for both \u003cstrong\u003eR22 and R407C systems\u003c\/strong\u003e, this valve features a 2.5-ton nominal capacity and a \u003cstrong\u003estraight body configuration\u003c\/strong\u003e with 3\/8\" x 1\/2\" ODF sweat connections. The heavy-duty \u003cstrong\u003estainless steel power element\u003c\/strong\u003e resists corrosion and prevents capillary tube fatigue, while the 5-foot capillary length provides installation flexibility in tight evaporator housings. As a \u003cstrong\u003ebalanced port TXV\u003c\/strong\u003e, it maintains stable superheat control across varying head pressures, making it a reliable choice for commercial refrigeration and air conditioning maintenance. This unit serves as the \u003cstrong\u003edirect replacement for 109055\u003c\/strong\u003e, ensuring seamless mechanical compatibility during field retrofits. Utilizing a \u003cstrong\u003eHC medium temp charge\u003c\/strong\u003e, it optimizes evaporator efficiency and prevents liquid slugging, ensuring long-term compressor protection and system stability for professional contractors.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStable Superheat Control:\u003c\/strong\u003e The balanced port design compensates for fluctuating head pressures, maintaining precise refrigerant metering.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Drop-In Replacement:\u003c\/strong\u003e Specifically engineered to replace the \u003cstrong\u003eAlco 109055\u003c\/strong\u003e without requiring extensive piping modifications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Features a \u003cstrong\u003estainless steel diaphragm\u003c\/strong\u003e and power element for superior resistance to corrosion and vibration-induced failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Refrigerant Compatibility:\u003c\/strong\u003e Rated for use with both \u003cstrong\u003eR22 and R407C\u003c\/strong\u003e, providing versatility for legacy systems and retrofits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Equalization:\u003c\/strong\u003e Optimizes performance in systems with high pressure drops across the evaporator coil.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCommon Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs the HFES 2.5 HC compatible with R410A systems?\u003c\/strong\u003e\u003cbr\u003eNo, this specific valve is charged and calibrated for \u003cstrong\u003eR22 and R407C\u003c\/strong\u003e.
