V Linear actuator
V series linear actuators are used when precise linear adjustments are required to control elements in heating, ventilation and air conditioning systems as well as in industrial applications.
V series linear actuators are available with actuating forces of 400 N bis 5000 N and a maximum stroke of 85 N.
The design of the housing made of die-cast aluminium and zinc in combination with permanently lubricated gearing with sintered-bronze bearing bushes ensures their suitability for use in a harsh operating environment. The technical construction mirrors that of series N actuators. End position limit stop is force-dependent. The standard scope of supply includes a limit switch for each end position. These are designed as changeover switches and can also perform supplementary functions such as end position indication or sequential control tasks.
Additional force and auxiliary position switches as well as potentiometers are also available. Fitting a relay makes it possible to control several actuators simultaneously via a common contact. The respective position of the valve is indicated by “Open/closed” markings on one of the columns of the stroke unit in conjunction with the bearing surfaces of the spindle nut. A solid flange is available to mount the actuator. A driver pin is included for connecting the actuator with the threaded spindle.
