K-TORK high-performance, rotary vane actuators are designed for long life and
precise control of ¼-turn valves. With only one moving part, the simplistic
design provides years of service in demanding, high cycle, fast operation and
critical modulating applications.
- No cranks or gearing – NO BACKLASH or “slop” results in smooth and
accurate positioning of the valve.
- Long Maintenance-Free Life – 2 million strokes GUARANTEED / 3-YEAR
Performance Warranty.
- Compact Design – High torque-to-size ratio fits into tight spaces.
- NAMUR Accessory Mounting – Standardized solenoid valve, limit switch
and positioner mounting interface meets International VDI / VDE 3845 provisions.
- Totally Enclosed – No dangerous external moving parts or pinch
points.
- Low Friction – Provides smooth operation, 40-150 PSI working
pressure, rated to 225 PSI overpressure.
- Linear Torque Output – No loss of torque in at mid-stroke or side
load to valve or actuator.
- Control Accessories – Complete range of modular “stack-up” control
accessories mount easily to the actuator.
- Corrosion Resistant – Two-stage stoved epoxy finish and stainless
steel fasteners and travel stops.
