Precise control of valve gates is provided by a new electric servo linear actuator from Tol-O-Matic Inc., Hamel, Minn. The ServoGate actuator replaces hydraulic manifolds and power systems used for valve-gate control and sequencing. A threaded rod connected to the valve gate passes through the hollow shaft of the linear actuator. The actuator delivers a continuous force of 500 lb as well as fast (less than 0.5 sec) gate movements. The actuator is operated by Tol-O-Matic’s Axiom Plus PV brushless servo controller. Windows-based software allows for point-and-click programming of the valve gate. The system is water cooled to operate at up to 400 F.
