Caleffi Z45P Z-one™ 3/4" Press 2-Way Motorized Zone Valve with Auxiliary Switch, 7.5 Cv, 24V

The Z-one™ valve is a truly universal zone valve that can be used in a wide range of commercial and residential applications; from fan coils to baseboard, radiant to high rise, the Z-one™ is the professional’s valve of choice. The Z-one™ can be used in both chilled or hot water and low pressure steam applications. With Delta P close off pressures of up to 75 PSI, the Z-one™ outperforms all other zone valves. 

• A snap-on actuator allows for fast installation and easy replacement with a convenient in-line push button.
• Compact design provides quick and easy installation, the Z-one valve fits perfectly inside baseboards and fan coils. Available with choice of NPT, sweat and press fittings for ease of installation and maintenance.
•  Suitable for all types of systems - made with materials compatible with chilled or hot water up to 240°F, 15 psi steam, and open or closed systems.
• A gear ratio of 21:1 in the actuator increases torque for high close-off pressure and increases closing time to reduce water hammer.
• Hermetically sealed end switch in 24V actuators requires no minimum current load allowing multiple end switches connected in parallel to zoning panel.
• Low power consumption allows up to five valves per 40 VA transformer.
