WOODWARD 5233-2089 PFAV Valve Regulator Module

The WOODWARD 5233-2089 is a precision-engineered pressure regulator module designed for diesel engine systems where consistent pressure control directly impacts performance. Commonly used in fuel management and valve actuation circuits, this module helps maintain optimal engine operation by delivering stable pressure regulation even under fluctuating load conditions. It’s particularly effective in applications requiring rapid response to pressure variations, such as marine propulsion systems or industrial generator sets.

Engineers working with heavy-duty diesel systems from manufacturers like Shangchai and Weichai frequently specify this module for retrofitting older installations or maintaining critical engine parameters. The PFAV series’ modular design allows straightforward integration with both legacy and modern control architectures. Our inventory includes complementary Woodward components such as the 8521-0312 UG-10D controller and 9907-162 digital governor, enabling comprehensive system replacements or upgrades.

This module’s technical strengths lie in its vibration-resistant construction and electromagnetic interference protection – crucial features for marine and mobile equipment applications. The ±3% stabilization accuracy ensures consistent fuel delivery patterns, which directly impacts combustion efficiency and emissions compliance. While the 7°C operating temperature rating might seem restrictive, field tests show it performs reliably in controlled engine room environments when installed per manufacturer guidelines. The compact 1 mm footprint proves particularly valuable when retrofitting space-constrained installations.
