Design Features	N/A Piston Aluminum alloy, designed for the most demanding applications. Piston bearing Low friction wear band centers the piston for extended life. Piston Seal A double acting, Per- and Polyfluoroalkyl Substances (PFAS)-free Polytetrafluoroethylene (PTFE), O-ring energized seal minimizes friction and requires an extremely low breakaway force. Provides a much longer life than conventional O-rings. Pinion High strength steel, plated for corrosion resistance. Precisely machined gear minimizes wear and backlash. Piston Rack Precision engineered tooth profile and wide engagement with pinion minimizes wear and maximizes strength. An integral safety bar (Models 5000 and 11000 feature interlocked tooth geometry to prevent pinion blowout.) prevents any possible pinion blowout. Pinion Bearings A proprietary high wear, low friction acetal compound extends life. Pinion Seals Nitrile, specially lubricated for life. Lubrication Groove Unique lubrication groove between the piston seal and piston bearing holds the proper amount of grease where it is needed for maximum life. Thrust bearing Designed for maximum life. Fasteners 304 stainless steel are high strength and corrosion resistant. End Caps Special aluminum alloy for durability. Powder coated for corrosion resistance and durability. Optional spring return end caps have restrained springs for easy installation. Housing Extruded aluminum alloy, precision machined with a proprietary hard coat finish internally and externally to guard against wear and corrosion. Piston Heel Bearing Large acetal bearing controls gear backlash and eliminates rack fatigue.
Advantages	N/A 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 +/-10º 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). Custom Options These include Fluorocarbon (FKM) seals, high temperature trim up to 250º F (121º C), special finishes, stainless steel pinions, special mounting configurations and special coupling configurations. Imperial or Metric Mounting
Operation Principles	N/A Double-Acting For clockwise operation, Port 2 (P2) is open to atmosphere and air pressure is directed to Port 1 (P1). As the pistons move apart, the pinion rotates clockwise. The linear movement of the pistons is converted to rotary motion by the piston racks and the output pinion gear. For counterclockwise operation, Port 1 is open to atmosphere and air pressure is directed to Port 2. The pressure differential moves the pistons together, rotating the pinion counterclockwise.
Accessories	N/A Numerous accessories are available as optional components to interface with the Tork-Mate® 890 series actuators. Mounting kits are also available.
