servomotore VMM40 VMM40

The CENTRA VMM20, VMM30 and VMM40 servomotors are special geared motors with high actuating force for heating applications, manufactured according to the latest knowledge and possibilities. Preferably used with three-way and four-way mixing valves with sockets and flange connections. Proven CENTRA quality and long service life. The actuator is equipped with 2 limit switches (set to 90°) to limit the travel. Manual adjustment is carried out via a release button in the cover and a hand lever. The position indicator of the VMM is integrated in the cover and has a reversible visual scale.
