Product Overview

The Woodward 8235-650 (ProAct PISC II) is a high-torque, all-electric actuator designed for precise engine throttle and fuel control. It manages air and fuel mixtures through integrated butterfly valves, optimizing combustion efficiency and minimizing leakage in both gaseous and diesel-fueled engines.

Technical Specifications

Engineering Advantages

• Optimized Fuel Sealing: Uses precision-machined tolerances and Parker 2-255 O-rings to trap the fuel/air mixture, preventing leakage and meeting emission standards.

• High-Speed Actuation: Provides rapid rotational response to governor signals, ensuring instant compensation for load changes, preventing overspeed or stalling in critical applications.

• Versatile Fuel Compatibility: Designed to withstand both gaseous fuels and diesel, simplifying inventory management for mixed-fuel fleets.

• Rugged Mechanical Integration: Compact and lightweight (1.65 kg) with a robust mounting interface, ideal for installation in tight engine compartments with high-frequency vibrations.

FAQs

Does this actuator require an external oil supply or hydraulic lines?

• No, the 8235-650 is a fully electric actuator, eliminating the need for hydraulic or pneumatic systems.

What maintenance is required for the O-ring seals?

• Inspect and replace the Parker 2-255 O-rings during standard engine overhauls to maintain pressure integrity.

How do I verify the unit is 100% Brand New?

• Each unit is supplied in original, factory-sealed packaging, with manufacturer documentation and a unique serial number for verification.

Can this actuator handle high-temperature intake air?

• Yes, the actuator supports flow medium temperatures up to 85°C, making it suitable for turbocharged applications with high intake air temperatures.
