Key Features:
- Two-stage mechanical feedback for high accuracy
- Nozzle-flapper pilot stage for fast response
- Any mounting position (fixed or movable)
- Available in aluminum or steel body construction
Application Scenarios: Aerospace flight control actuators, metallurgical plant hydraulic systems, injection molding machines, fatigue testing rigs, and precision motion platforms.
Working Principle: An electrical command signal drives the nozzle-flapper pilot stage, which positions the spool via mechanical feedback. The spool metering edges regulate hydraulic flow to the actuator proportional to the input signal.
Installation & Notes:
- Install in any orientation per ISO 10372-04-04-0-92
- Maintain hydraulic fluid cleanliness per ISO 4406 recommendations
- Use appropriate filtration: β10 ≤ 75 (10 μm absolute) for functional safety, β5 ≤ 75 (5 μm absolute) for longer service life
- Higher temperature options available up to 400 °F
