Description: The linear actuators are designed to provide highly accurate precise positioning for a closed-loop control with a minimum number of moving parts, which prolong the life of the actuator. The linear actuators provide a quick response time and can be used for different applications. The fast-acting actuator is completely self-contained. It requires only a firm mounting , appropriate linkage to the control and electrical connection to the speed control unit. The actuators are not sensitive and therefore can operate in any position. The actuators are compatible with GAC's standard speed control units.
