E050 Cartridge DDV Proportional Valve: A Motorsport development of the established Moog D633-7 design. This Proportional Direct Drive Valve (DDV) uniquely uses a linear motor to actuate the flow spool. The DDV technology achieves the robust function of a proportional valve with the speed and accuracy of a servovalve. This miniature valve has a flow capability of up to 18 L/min, meeting the requirements of the majority of Motorsport applications. The cartridge design permits compact packaging on applications where multiple valves are required to be mounted in a single manifold. The robust mechanical design is optimized to meet the extreme performance and environmental demands of the Motorsport industry.
