Overview
The Woodward 8901-457 CPC (Current-to-Pressure Converter) Valve is a flagship model in Woodward’s CPC series, designed to deliver linear, repeatable hydraulic control in harsh environments. It transforms standard 4–20 mA control signals into 0–25 bar hydraulic pressure, enabling accurate positioning of single-acting actuators and servo systems.
Its 316L stainless steel valve body and IP65-rated die-cast aluminum housing ensure corrosion resistance and durability in offshore platforms, ship engine rooms, and chemical plants. The CPC valve features LED indicators, Modbus interface, and single-port diagnostics, simplifying integration and maintenance.
The 8901-457 is compatible with Woodward control systems such as 505, 505E, and MicroNet, and supports hot-swap replacement without system shutdown. Its fast response time (<10 ms) and repeatability (±0.5% FS) make it ideal for critical control loops in rotating machinery.
