      ACTUATECH PNEUMATIC ACTUATOR DESIGN

      GHPD scotch yoke actuators are designed to operate heavy duty remote control af ball, butterfly and plug valves in quarter turn operation, either for ON/OFF and modulating duty. Fabricated in carbon steel frame, electroless nickel-plated cylinders and chromium-plated piston rod ensure optimum performance. Thanks to the special working system that reduces the friction and avoids the stick-slip effect, the heavy duty actuator provides efficient service with minimum maintenance.

      TECHNICAL FEATURES AND MATERIALS

      • The scotch yoke rotary lever system allows generating high starting torque suitable for operate on ball, butterfly and plug part turn valves.
      • Strong Bronze bushings ensure a smooth cycle for long lasting life without maintenance.
      • Robust Thrust bar for high transverse forces and proper support.
      • Piston rod and Trust bar are chrome-plated to ensure minimum friction and best corrosion resistance.
      • PTFE Graphite Filled sliding ring supports the piston to avoid stick-slip effect and reduce the friction.
      • Multiple external studs structure for the cylinder and welded housing provide axcellent solidity and resistance.
      • Housing and cylinder caps internal corrosion protection by coating.
      • 200 micron External protective coating.

      The Scotch Yoke design with 9 Bushings minimizes the rotation and the sliding friction of the steel parts ensuring a long life without maintenance.

      Nr. 2 symmetrical strong yoke bushings to support the rotation drive

      Nr. 2 symmetrical sliding blocks against the asymmetrical thrusts between linear piston force and yoke rotary torque

      Nr. 1 piston rod bushings

      Nr. 2 guide thrust bar blocks

      Nr. 2 spring cartridge slem bushings

      Actuators Nominal Torques: from 2000 Nm to 32000 Nm

      Mounting Flange: according with DIN/ISO 5211, DIN 3337, F25-F30-F35

      Rotation Angle: 100° (-5° +95°)

      Stroke Adjustment: 10°

      Operating Pressure: from 3bar to 8.5bar (Maximum pressure that can be applied to a fully stroked actuator against the travel stop). The torque is directly proportional to the operating pressure. For the simple acting (spring return) actuators the reverse torque is performed only by the spring action, and is independent from the operating presure.

      Temperature range: Standard version -20°C to 80°C (Seal material NBR), Special version High Temperature -20°C to 150°C (Seal material FKM), Special version Low Temperature -50°C to 60°C (Seal material FVMQ).

      Operating media: compress filtered air not necessary lubricated, inert gases. For temperature under 0°C use dry air. In case of lubricated air use non-detergent oil compatible with the seal material.

      Design: according with EN 15714-3, ISO 5211, ISO 12490.

      Type: Spring return Nc, Spring return No, Double acting.

      Torque output design: Symmetric Scotch Yoke - or - Canted Scotch Yoke.
