Valve Accuators
The XTronica XH Series Hydraulic Actuators are high-performance quarter-turn actuators designed for reliable valve automation in marine, offshore, and industrial applications. Engineered to convert hydraulic energy directly into mechanical rotary motion, the XH Series utilizes a robust rack-and-pinion mechanism to deliver high torque output within a compact and efficient design.
Description
Suitable for a wide range of quarter-turn valves, including butterfly valves, ball valves, and plug valves, the XH Series is built for long-term operation in demanding environments. The actuator design incorporates low-friction bearing arrangements, utilizing polymer bearings in smaller models and ball bearings in larger units to ensure smooth operation, reduced wear, and extended service life. A key advantage of the XH Series is its maintenance-friendly design, allowing servicing and repair activities to be performed while the valve remains installed, minimizing operational downtime and simplifying maintenance procedures.

Operating principle
The XH Series uses a hydraulic piston and rack mechanism to generate rotational movement.
- Hydraulic pressure drives the piston assembly.
- The rack engages with a pinion gear.
- Linear piston movement is converted into rotary output.
- The rotary output operates quarter-turn valves with high efficiency and torque.
This proven rack-and-pinion design ensures reliable valve operation while maintaining compact actuator dimensions.
