Icma 341 | Male/female two-way full bore zone ball valve, with servomotor

Function

The zone valves are aimed at automatically controlling and diverting the fluids in
heating, air conditioning and sanitary water systems.
They are controlled by a servo-control, connected to a room thermostat provided with
automatic return function, regulating the ambient temperature. All servomotors are
equipped with an auxiliary micro-switch to control the pump.
This product, easy to install, shows high hydraulic performance in reduced sizes, this
makes it specially suitable for zone heating installations.

Advantages of the zone ball valves:
– Excellent seal
– Quick opening/closing time
– Low pressure drop rates
– Operation under high differential pressures

Advantages of the ICMA zone valves:
– Soft seat ball movement, valve opening torque < 45 lbf-in 6 Nm
– Quick connection system
– The motor can be used manually as a release device in the event of power failure
– Highly reliable motor, manufactured in Switzerland
– High precision gears, in sintered metal materials
– Low noise level .
– Motor start-up torque doubled if compared with the valve body
– Quick and repeatable motor lock/unlock, without damaging the motor or the valve
– Severe and rigorous factory testing and quality control procedure (50.000 cycles)
