Product Overview

zone valves
Z series
Function
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 3/4" 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.
