Abstract A generalized PCM digital hydraulic valve includes reverse valve and two sets of several flow control valves. Each flow control valve has throttle holes with different sizes. The throttle area is linearly binary code between the low-level valves and non-linear code between the high-level valves. The valve core is driven by electromagnet. The flow and direction can be controlled by controlling the on-off states of all electromagnets. Its advantages are high reliability, wide regulation range, low sensitivity to medium pollution and simple structure.
