ABB can provide valve positioning systems based on several different technical approaches. Pilot valve interface involves retaining the existing low pressure servo motor and using a pilot valve actuator to position the servo motor pilot valve. This approach provides reliable control and a cost effective means of upgrading an existing system.
Why ABB?
ABB has extensive experience providing pilot valve actuator control for a variety of existing hydraulic control systems. These actuators are custom designed for their application using industry standard components and approaches. The valve actuators include the necessary hydraulic components for proper valve positioning, as well as position feedback for the control system.
- Precise pilot valve positioning
- Increased reliability by removing existing governor system
- Redundant configuration available for servo valve and position feedback
