Caleffi Z-one™ Z55P 2-Way Zone Valve With Auxiliary Switch, 3/4 in Nominal, Press End Style, 300 psi Pressure, 2.5 Cv, 24 VAC
cUL Listed | CE Certified | FM 21654 | ISO 9001 | UL 873 | UL 1995 sec 18 Approved for Air Plenum and Ducts

Caleffi Z-one™ Zone Valve, 2-Way, Series: Z Series, 3/4 in Nominal, Press End Style, 300 psi Pressure, 2.5 Cv Coefficient of Volume, 24 VAC, 0.4 A, 32 to 240 deg F Water, 50 psi Differential, Screw Terminal Electrical Connections, Forged Brass, 5-5/8 in OAL

Z-one™ valves are used to automatically shut-off the flow or redirect hot and chilled water in hydronic systems, open systems, closed systems, low-pressure steam; and are UL listed for plenum installations. The motorized two-position, on/off, spring return Z1 series actuator has an end mounted push button for quick installation to the valve body. The actuator is equipped with or without an auxiliary micro-switch and models are either normally closed or normally open and with wire or terminal connections. The high temperature zone valve body Z2 series is 2-way straight through and the valve body Z3 series is 3-way diverting or mixing. The Z1 series actuator is easily attached by a push button lock and requires no tools. The Z-one™ valve provides 100% bubble-tight seat close-off leakage. The high temperature and high close-off performance characteristics of these zone valves, combined with the compact size, makes them suitable to fit inside baseboards or directly in fan coil units. Z-one™ valves are available with 1/2 to 1 in press fittings, the Presscon™ copper tail-piece with union nut, making installation and maintenance fast, easy and efficient. Special slots in the EPDM O-ring allows fluid to leak during system testing if unpressed and provide a perfect leak proof seal when completely pressed. Some models are low-lead brass, for domestic hot water applications.
