The K/KM-1400 Scotch yoke actuators are specifically designed for use with quarter-turn valves. The large output torque range offered by Radius ensures that our actuators match the operational characteristics of plug, ball or butterfly valves; or any device requiring precise and reliable 90° rotary motion.- Carbon steel scotch yoke mechanism available in symmetric form.
- Modular construction allows the air cylinder and the spring cartridge to be assembled to either side of the central body.
- The air cylinders are nickel plated as standard to improve corrosion resistance and reliability.
- An internal chrome guide bar insures proper support of the piston rod.
- Provided with bronze bearings and sliding blocks for smooth operation and extended service life.
- For the spring return version the spring is supplied in a welded spring cartridge to ensure safety when disassembling. The spring cartridge can only be removed when the spring is released.
