Emerson 063962 XC-726HC-4B Power Element, 4m Capillary, R22/R407C, for T/ZZ Series TXVDescription
The Emerson XC-726HC-4B (PCN: 063962) is a power element/thermobalance designed for T-series (TCLE/TJRE/TER) and ZZ-series (ZZCE) take-apart thermostatic expansion valves. It features a 4-meter capillary tube and is charged for R22/R407C refrigerants, optimized for medium-temperature HVAC&R applications (-29℃ to +10℃). This UL/CE-certified component precisely senses evaporator outlet temperature, regulates superheat, and ensures stable valve operation under varying load conditions (25%–100%). With a maximum working pressure of 31 bar, it serves as a direct, interchangeable replacement for Emerson TXV power heads, ideal for commercial AC, chillers, and medium-temp cold storage systems.
Product Details
Emerson XC-726HC-4B (063962) Power Element for T/ZZ Series Thermostatic Expansion Valves
Key Features & Benefits
Refrigerant Compatibility: Exclusively charged for R22 and R407C, making it ideal for air conditioning, chillers, and medium-temp cold storage systems.
Medium-Temp Operation: Designed for -29℃ to +10℃ (-20°F to +50°F) evaporating temperatures, delivering stable superheat control under partial loads (down to 25%).
4m Capillary Tube: Equipped with a 4-meter (13ft) capillary for flexible installation in various system layouts.
Modular Interchangeability: Directly replaceable with other XC-726 series power elements in T/ZZ series TXVs, reducing inventory and service costs.
