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 A1 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.

Air separators are used to continuously remove the air contained in the
hydronic circuits of heating and cooling systems. The air discharge
capacity of these devices is very high. They are capable of removing
automatically all the air present in the system down to micro-bubble level.
The circulation of fully de-aerated water enables the equipment to operate
under optimum conditions, free from any noise, corrosion, localized
overheating or mechanical damage. Micro-bubbles, fuse together,
increase in volume until they become large enough to rise to the top where
they are automatically released.

Caleffi Series 676 Two-way Thermoelectric Zone Valve
Zone valves are used to control hot and chilled water in heating and air conditioning
systems. Coupled with an electro-thermal control actuator and
managed by a room thermostat, they allow automatic on/off control of the
hydronic circuit on which they are installed.
Their special feature is their compact size and they can therefore be installed
almost anywhere including baseboard or directly in fan-coil units.
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 A1 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 coil units.
