• Spring return

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 pushbutton 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 two-way straight through and the valve body Z3 series is three-way diverting or mixing. The Z1 series actuator is easily attached by a pushbutton 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, a 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.
