Designed as a \u003cstrong\u003e15-ton expansion valve\u003c\/strong\u003e, this component is optimized for \u003cstrong\u003eR22 expansion valve\u003c\/strong\u003e applications and \u003cstrong\u003eR407C refrigerant control\u003c\/strong\u003e. It features a 5\/8\" x 7\/8\" ODF sweat connection and a straight-through body configuration for streamlined integration into existing liquid lines. The inclusion of an \u003cstrong\u003eexternally equalized TXV\u003c\/strong\u003e design ensures accurate superheat maintenance even in systems with significant evaporator pressure drops, preventing hunting and improving overall evaporator efficiency. With a 5-foot capillary tube and a Maximum Operating Pressure (MOP) 100 PSI charge, the \u003cstrong\u003eAlco 063103\u003c\/strong\u003e protects the compressor by limiting suction pressure during high-load startups. This \u003cstrong\u003eAlco T-Series valve\u003c\/strong\u003e is a standard-setting choice for technicians requiring reliable, \u003cstrong\u003ecommercial HVAC expansion valve\u003c\/strong\u003e performance in medium to large-tonnage equipment.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits:\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e15-ton nominal capacity\u003c\/strong\u003e provides robust refrigerant metering for large-scale commercial air conditioning and refrigeration.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual refrigerant compatibility\u003c\/strong\u003e allows for seamless operation with R22 and R407C systems.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal equalization\u003c\/strong\u003e compensates for internal pressure drops, ensuring stable superheat and preventing coil starving.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMOP 100 PSI charge\u003c\/strong\u003e acts as a safeguard, protecting the motor from overload during hot pull-downs.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eODF sweat connections\u003c\/strong\u003e (5\/8\" inlet, 7\/8\" outlet) ensure leak-free, brazed joints in high-vibration environments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e5-foot capillary tube\u003c\/strong\u003e offers flexible sensing bulb placement for optimized thermal response.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions:\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the MOP 100 PSI feature benefit the system?\u003c\/strong\u003e\u003cbr\u003e\nThe Maximum Operating Pressure charge limits the expansion valve from opening too far during high-load conditions, such as after a defrost cycle or initial startup. This prevents the suction pressure from rising above 100 PSI, protecting the compressor motor from excessive torque and potential failure.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen should this externally equalized valve be used over an internally equalized model?\u003c\/strong\u003e\u003cbr\u003e\nAn externally equalized valve like the 063103 is mandatory in systems where the pressure drop across the evaporator is significant. It senses the actual pressure at the evaporator outlet, providing a more accurate superheat reading than internal sensing, which leads to better coil utilization.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan this valve be field-repaired or adjusted?\u003c\/strong\u003e\u003cbr\u003e\nWhile the superheat is adjustable to fine-tune system performance, the power assembly and internal components are matched for the 15-ton rating. Always use a calibrated pressure-temperature chart for R22 or R407C when setting superheat to ensure the compressor remains protected from liquid slugging.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
