MVA43

Electrothermal actuator for zone valves and terminal units, connectable to CONTROLLI VZS 2-way globe valves, VMZ 3-way globe valves and VTZ 3-way 4-port globe valves. It consists of an expanding thermostatic element which, upon receiving the 24 Vac command, causes a piston to extend, pushing down the valve stem, overcoming the return spring of the valve body.

The difference between MVA43 and MVA41 is that the MVA41 comes with a cable; therefore, MVA43 can be used as a replacement for MVA41, retaining the existing cable.

The D41 auxiliary micro switch accessory can be ordered separately, whose function is usually to stop the circuit pump when the valve is closed.
