MTP – electric linear actuator

Usage

Electric linear actuator MTP actuators are used for remote two-position or three-position control of the valves by a reverse rectilinear motion. The MODACT^® MTP CONTROL actuators are fitted with an electronic position controller.

In association with the valve exhibiting a suitable control characteristic, they form a position servo-loop. The output pull-rod of these actuators is automatically brought into a position corresponding to the input signal value of the controller. The actuators can be used even for other devices for which they are in respect of their characteristics and parameters suitable. In some special cases, the contemplated use of the actuators should be consulted with the manufacturer.
