Detailed Introduction

   Features

  The patent‑designed parallel, dual‑guide fork transmission box can provide high opening torque for quarter‑turn valves.

  Parallel, dual guide rods can withstand lateral loads and provide support for the piston rod.

  Composite bearing structures can provide reliable, smooth operation and extend the service life of actuators.

  Piston bearings reduce friction between the piston and cylinder wall, enabling the cylinder to achieve a self‑lubricating effect.

  The guide rod coating boasts high strength and excellent corrosion resistance, minimizing friction to the lowest possible level.

  The cylinder wall features high strength, corrosion resistance, and reliability.

  The built-in guide linkage design makes the cylinder structure more compact.

  The fully enclosed, all-weather protective carbon steel housing is robust and reliable, while the internal coating provides corrosion resistance.

  The external travel limit bolts are precisely adjustable within a full range of 90±5°.

  Low-speed hysteresis and rapid response enhance usability in regulating applications.

  Provides both asymmetric and symmetric fork designs, suitable for valves with different characteristics.

  Special coatings can be used on offshore platforms and in highly corrosive environments.
