Icma 320 | Two-way zone valve with electrothermic actuator

FUNCTION

The zone valves Art.300-301-302 are used to adjust
and balance the flow in heating, cooling and sanitary
systems. The range includes a two-way zone valve
(Art.300), a three-way zone valve (301) and a fourway zone valve with adjustable interaxe (Art.302) all
available with male tail.
The zone valves are combined with electrothermic
actuators Art. 979 (electrothermic actuator normally
close ON-OFF) or Art. 982 (electrothermic actuator
normally close with micro switch).
Our thermostatic heads can be installed with remote
sensor 992 e 995.

OPERATING PRICIPLE

When a room thermostat operates, the thermo-electric actuator causes the opening or closing of the valve obturator controlling
the thermal carrier fluid. The manual knob on the valve can be used for any preliminary opening/closing operations. It is
removed to fit the thermo-electric or the thermostatic actuator with remote sensor by unscrewing the lower metal ring
