The Z-one, a two-position spring return zone valve, is used in heating and air-conditioning systems.
The Z-one series consist of a Z1 actuator which is easily attached to a Z2 (2-way) or Z3 (3-way) valve body. Z1 actuator is equipped with or without auxiliary switch.
The Z-one actuator has a synchronous motor that winds the return spring and moves the valve paddle to the desired position. When power is removed the actuator spring returns the valve paddle. 24V actuators use a sealed reed switch for end switch, requiring no minimum current load.

The Z-one series two-position spring return with removable actuator zone valve. Z1 series actuator is normally closed (NC) or normally open (NO) 24 V to 277 V 50/60 Hz, 5 W, 7 VA, with or without auxiliary micro-switch {(24 V: 0.0 min,0.4A max, 24 V) (120-277 V: 5.0A, 230 V)}, Auxiliary micro-switch for 24 V actuator is a sealed reed switch requiring no minimum current load, includes leads or terminal block (24 V only); Lost motion transmission disengagement actuation mechanism; Quick-connect actuator-to-valve body assembly (no fastener); ambient temperature from 32 to 104 deg F (0 to 40 deg C) for 120 V, 208 V, 230 V, 277 V actuators with micro-switch; 32 to 125 deg F (0 to 50 deg C) for 24 V actuators; 32 to 170 deg F (0 to 77 deg C) for 120 V, 208 V, 230 V, 277 V actuators without micro-switch. Z2 (2-way) series and Z3 (3-way) series are forged brass (2-way and 3-way 1/2” and 3/4” sweat valve bodies pn Z207411, Z207433, Z307433, Z207533, Z207537 and Z307537 are low-lead brass [<0.25% lead content] certified by ICC-ES file 1360). Valve body rated at 300 psi (20 bar), 15 psi (1 bar) steam. Temperature rated 32 to 240 deg F (0 to115 deg C). Valve stem stainless steel, EPDM seals, flows: 1.0, 2.5, 3.5, 5.0 or 7.5 Cv. Close-off seat leakage: 100% bubble-tight. Connections and sizes: 1/2”, 3/4", 1" and 1 1/4” sweat or 1/2”, 3/4" and 1" NPT female threads, 1/2" SAE flare, inverted flare, 1" straight male threaded union, and 1/2”, 3/4" and 1" press, PEX crimp or PEX expansion end connections with unions. Actuator approved to UL 873, cUL listed and CE, and UL 1995 section 18 air plenum and ducts rating. US Patent 7,048,251.

Description 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 ½ to 1 inch 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.
