Automatic air vents are used in the closed circuits of solar heating systems. They allow air contained
in the fluid to be released automatically during the filling process, through a valve operated by a float
in contact with fluid in the system.
The shut-off valves are used in combination with the automatic air vents to isolate them after filling
the circuit of solar heating systems.
.These series of products have been specially made to work at high temperatures with a glycol medium.

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.
