Pressure Compensated Electro-Hydraulic Proportional Flow Control Valve

The requirement for reliable, precise positioning of functions with remote actuation promoted the development of a pressure compensated electro-hydraulic proportional flow control valve. Lower horsepower consumption, contamination insensitivity, built-in position feedback, and manual operation in case of an emergency were the prime design criteria. These concepts are discussed in this paper and along with the advantages of utilizing these concepts in typical mobile hydraulic circuits.
