Servo motors

Servo motors can be assembled, using suitable flanged adaptors, to 2-ways ball valves and to manual 3-ways ball valves. They are assembled directly on the motorized 3-ways ball valves. Once this coupling has been performed, the valve can be opened or closed remotely. Alternatively, the servo motor can be excluded and the valve can be operated manually.

Castel manufacturers servo motors with a variety of operational characteristics: they are manufactured with a synthetic, self-extinguishing housing that covers the motor, the control and cut-out electronics based on the gear reducer torque and the self centring fixing system of the valve rod.
In the event of a power outage to the servo motor, the gear reducer can be disengaged using the specific lever, to permit manual use of the valve.
Furthermore, auxiliary contacts for switching are available for remote control of the valve status.
