MVA41

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 a 24 Vac command, causes a plunger to extend and push down the valve stem, overcoming the return spring of the valve body.

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

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