The Tork-Mate® 890 series, extended-life actuators are ideal for the operation of 90°-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.
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).
