The Tork-Mate® 890 series, extended-life actuators are ideal for the operation of 90º-turn devices such as butterfly valves, ball valves, plug valves, damper valves, and other devices. Tork-Mate® pneumatic actuators have features that are unique, providing many benefits to the user looking for worry-free service.
- TMHC 2324
A proprietary two-step, hardcoat process that offers superior protection on interior and exterior housing surfaces, TMHC 2324 also ensures maximum life from the piston seals, piston bearings, and heel bearings. - NAMUR Mounting
Tork-Mate® 890 series actuators meet the latest NAMUR standards, allowing direct or close coupling of NAMUR-designed accessories. The pinion interface features a positive, international standard drive for positioners, switches, and other accessories. The solenoid interface allows direct acceptance of any NAMUR-designed control valves. - Modular
Easily removable end caps and modular spring packs simplify the conversion from double-acting to spring-return configurations. - Travel Adjustment
The Tork-Mate® 890 series actuators feature pinion travel stops that allow a full ±100 of valve travel adjustment. As an option, extended-stroke adjustment screws can be added for inexpensive throttling applications. - Extended Cycle Life
Special piston seals provide greatly extended life compared to standard O-ring actuators. All other bearings, seals, and components have been engineered to provide superior and extended service lives. - Blow-out Proof Pinion Gear
In addition to the stainless-steel pinion retaining ring, the Tork-Mate® 890 series actuators feature a unique, internal safety bar. - Operating Ranges
Tork-Mate® 890 series, double-acting actuators produce guaranteed minimum torque outputs up to 17,466 inch/pounds (1973 Nm). - Imperial or Metric Mounting
