Hydraulic Actuators

Janatics Hydraulic Actuators are engineered for high-torque and heavy-duty applications, delivering reliable performance in critical process environments where pneumatic or electric solutions may not be sufficient. Designed for demanding industries such as oil & gas, power, steel, and heavy process plants, these actuators provide precise control, high force output, and fail-safe operation under extreme conditions.

Design & Construction

Built for robustness and long service life, Janatics Hydraulic Actuators feature:

  • Heavy-duty cylinder and housing construction

  • High-strength alloy steel components for critical load-bearing parts

  • Precision-machined piston and rod assembly

  • High-performance sealing system for leak-proof operation

  • Corrosion-resistant coatings for harsh environments

Operating Principle

Hydraulic actuators use pressurized fluid to generate high force or torque, making them ideal for large valve sizes and high-pressure applications.

  • Linear Hydraulic Actuators: Direct thrust for gate, globe, or knife gate valves

  • Rotary Hydraulic Actuators (Scotch Yoke): Convert linear motion into high torque output for quarter-turn valves
