servomotore VMM40-24 VMM40-24

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.
