The EL-O-Matic VP speed control plate is specially used where ordinary NAMUR style solenoid valve miss a speed control throttles. The speed control plate provides a speed regulating function (throttling) for both double and spring return actuators with a NAMUR air entry manifold in combination with a NAMUR solenoid. Both the flow restrictors are independently adjustable for both strokes. On spring return actuators, only the spring return stroke time can be regulated.
