Val-Matic’s motorized traveling nut and worm gear actuators are specifically designed to match the torque characteristics of the Val-Matic quarter turn valves. The actuators are built in accordance with AWWA Standard C542 for Electric Actuators and are equipped with externally adjustable stops for easy field adjustment. Motors are available to suit multiple speeds and voltages and are equipped with thermal overloads, torque switches and limit switches to protect the actuator and valve. A handwheel gear set with declutch is included to allow users to manually position the valve without electrical power.
Val-Matic’s traveling nut cylinder actuators are designed and built in accordance with AWWA C541 for Hydraulic Actuators. They provide reliable characterized closureand feature externally adjustable closed stops to control end of valve travel and for ease of adjustment. Cylinder heads and pistons are constructed of stainless steel. The one piece piston is fitted with a wear strip for long and reliable seal life. The cylinder barrels are available in stainless steel or non-metallic construction. Piston seals are self adjusting and wear compensating for extended life. The seals are suitable for air, oil or water supply media to 150 psig. Cylinder actuators can also be used with control systems.
Val-Matic’s worm gear actuators provide precise quarter turn actuation in accordance with AWWA Standards. They are standard on Plug Valves and available on Ball and Butterfly Valves. Worm gears include externally adjustable mechanical stops to control end of valve travel. Optional spur gear assemblies are provided to increase mechanical advantage thereby reducing the handwheel and nut input torques.
Val-Matic’s traveling nut manual actuators are designed to specifically match the torque characteristics of Val-Matic Ener•G™ Ball Valves and Val-Matic American-BFV® Butterfly Valves and are built in accordance with AWWA Standards. The traveling nut actuator provides characterized closure which allows the valve to slowly close during the last half of travel to reduce pipeline surges. Val-Matic actuators have the exclusive feature of externally adjustable stops rated to 450 ft-lbs of input torque.
