zone valves

Z series

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, and is 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 valve body. The actuator is equipped with or without auxiliary switch and

configured Normally Closed or Normally Opened with wire or terminal connections.

The zero leakage high temperature zone valve body Z2 series is 2-way straight through and the valve

body Z3 series is 3-way diverting. The Z1 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.

Dimensions Operating principle (4 17/32”)* 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.

Construction details Installation • Auxiliary switch The actuator contains an auxiliary microswitch to operate other devices. The 24 V actuators use a sealed reed switch, patent pending, which has been produced specifically for use with relays, boiler contacts (TT) and DDC systems. It requires no minimum current load. The 120 V - 277 V actuators, and actuator model number Z111000 HCS for applications requiring greater than 400 mA, use a conventional microswitch with silver contacts.
