The Z-one valve is a 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 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 is available in sizes from 1/2” to 1 1/4” sweat or NPT connections on the valve body, with a removable actuator. A snap-on actuator allows for fast installation and easy replacement with a convenient in-line push button.
A gear ratio of 21:1 in the actuator increases torque for high close-off pressure and increases closing time to reduce the water hammer. It is made with materials compatible with chilled or hot water up to 240° F, 15 psi steam, and open or closed systems. Its low power consumption allows up to five valves per 40 VA transformer.
