WebMechanical screw jacks and linear actuators are increasingly becoming the preferred choice of actuation over the equivalent hydraulic or pneumatic systems with advantages including simpler and smaller installation, a cleaner, healthier, quieter environment, lower energy costs with less maintenance. Web• Compact design, with balanced distribution of the weight on the valve • With two pistons in a given size cylinder, torque is doubled and the linear piston forces cancel one another so that the actuator output is purely torsional with no side loads on either the valve components or actuator bearings.
