Emerson 063962 XC-726HC-4B Power Element, 4m Capillary, R22/R407C, for T/ZZ Series TXV
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.
