Linear Actuators

Linear Actuators For Multi Purpose

Hydraulic actuators for valve position control and fail safe function.
Hydraulic linear actuators are specially developed and designed for the exact and dynamic operation of control valves in power plants and industrial applications.

The actuators will be constructed in detail according to customers’ requirements. Pleiger’s state of the art CAD system helps to propose the optimal technical solution to the customer as soon as possible.
