Tork-Mate 890 Series Advantages The Tork-Mate 890 Series extended life Actuators Travel Adjustment are ideal for the operation of 90 turn devices The Tork-Mate 890 Series Actuators feature pinion such as butterfly valves, ball valves, plug valves, travel stops that allow a full +/-10 of valve damper valves and other devices. Tork-Mate travel adjustment. As an option, extended stroke Pneumatic Actuators have features that are unique, adjustment screws can be added for inexpensive providing many benefits to the user looking for throttling applications.
