1 Z series zone valves R EGI S TERE S EN ISO 900:000 ert. n FM 64 UNI EN ISO 900:000 ert. n 0003 LEFFI 0/09 N Replaces 0/04 N Function Z-one valves are used to automatically shut-off the flow or redirect hot and chilled water in hydronic heating and air conditioning systems. The motorized two position, on/off, spring return Z series actuator has a end mounted push button for quick installation to valve body. The actuator is equipped with or without auxiliary switch and configured Normally losed or Normally Opened with wire or terminal connections. The zero leakage high temperature zone valve body Z series is -way straight through and the valve body Z3 series is 3-way diverting. The Z series actuator is easily attached by a push button lock and without tools. The high temperature and high close-off performance characteristics of these zone valves, combined with the compact size, makes them suitable to fit inside baseboard or directly in fan coils units.

3 Installation - The valve can be fitted either vertically or horizontally, with the actuator in any position, except upside down If it is installed inside a encloser it is important to ensure that there is adequate ventilation inside the encloser itself. - The three-way valve cannot be transformed into a two-way valve and vice versa. - When zone valves are installed, the direction of flow must be observed as shown in the diagrams below. - Two-way zone valves can be installed on both the flow and return sides; the direction of flow indicated by the arrow on the body of the valve must be observed. - Three way zone valve can be fitted with N actuator only (rotate 80 the valve body for NO application).

The 4 V actuators use a sealed reed switch, patent pending, which has been produced specifically for use with relays, boiler contacts (TT) and systems. The 0 V - 77 V actuators use a conventional microswitch with silver contacts. The auxiliary switch is activated when the valve is 60% open or when the actuator is manually opened. Manual opening The valve can be opened manually by moving the lever for opening it. When the power is restored the manual control is automatically overridden. The auxiliary switch in 4 V actuators is tripped when the unit is put into manual open position. This helps during start up to check if the wiring is correct without firing the valve electrically with the thermostat. Easy push button simple push of the button makes it easy to remove it from the body of the valve for maintenance or replacement operations. Warning: the actuator can only be used with valve bodies Z-Z3 series. Operation The actuator is fitted with a special mechanism for gradual movement of the valve paddle which provides smooth and quiet constant operation. Power-on full stroke run time is 60 seconds with power-off return time running less than 0 seconds, reducing or eliminating the effects of water hammer.
