Description
Zone valves are components that have the task of automatically regulating the flow of water in the system, to improve environmental comfort and energy efficiency.
This series of zone valves are equipped with a spring return shutter, a 24V servo control (quick release) which with progressive movements prevents any shocks due to the inertia of the motor.
The servocontrol is also equipped with an auxiliary microswitch, which allows additional devices, such as a circulation pump, to be activated when the valve reaches 60% of its opening. If necessary, it is possible to manually open the valve by acting on the opening lever, with the certainty that when the power supply is restored the system will automatically disengage.
