Woodward 9907-1200 Pressure Regulating Valve Control

Description

The Woodward 9907-1200 Pressure Regulating Valve Control, also known as CPC-II (Second Generation Current-Pressure Converter), is a high-performance electro-hydraulic control component designed to convert electrical signals to pressure signals for precise actuation control. It operates on 24V voltage, with a current range of 100-400A, and accepts a 4-20mA current setpoint input signal. Its maximum power consumption is 15W, and it functions reliably across a wide temperature range of -40 degrees Celsius to 70 degrees Celsius. With physical dimensions of 155mm (length) x 50mm (width) x 225mm (height) and a weight of 1.2kg, it is compact for integration into diverse systems.

Key technical features include high conversion accuracy of ±0.1%, a fast response speed loop bandwidth of up to 100Hz, and exceptional reliability with a mean time between failures (MTBF) of 100,000 hours. It also offers oil contamination resistance meeting ISO 20/16 standards, addressing common industry reliability issues related to fluid contamination. This unit provides stable, linear valve control, enabling precise oil pressure regulation to position single-acting steam turbine speed control valves, which supports improved turbine speed and load control while reducing mechanical wear. It is widely applied in industrial automation, energy, oil and gas, aerospace, and power generation sectors, particularly in process control systems, pneumatic actuation systems, and large generator sets.
