Description
Woodward 8516-187
Technical Specifications
- Brand: Woodward
- Part Number: 8516-187
- Product Type: Electro-Hydraulic Actuator
- Actuation Type: Linear, Double-Acting or Spring-Return
Functional Features
- Robust Construction: Designed to withstand continuous industrial duty cycles and harsh environmental conditions.
- Integrated Feedback: Equipped with high-resolution position transducers for accurate closed-loop control.
- High Reliability: Engineered with redundant sealing and premium bearings for extended maintenance intervals.
Application Scenarios
Used in power generation turbines, compressor anti-surge control, and high-pressure fluid regulation systems.
Performance Parameters
- Force Capacity: High thrust output suitable for large-bore control valves.
- Linearity: Excellent stroke-to-signal linearity for predictable control response.
Material Composition
Heavy-duty steel housing, precision-honed cylinder bore, and industrial-grade hydraulic seals.
Structural Characteristics
Compact, space-saving design with standardized mounting flanges and easily accessible hydraulic connections.
Working Principle
Translates electronic control signals into hydraulic pressure differentials across a piston, generating linear motion that is precisely regulated by continuous position feedback.
Installation Requirements
Ensure proper mechanical coupling to the valve stem. Route hydraulic tubing away from high-heat sources.
Usage Precautions
Maintain strict hydraulic fluid cleanliness standards. Perform regular stroke testing to verify mechanical freedom and seal integrity.
