Abstract
The function of any hydraulic control device is to control one or more of the following actuator output variables: direction, velocity, acceleration, deceleration, position or force. The control element controls the mechanical output variables by manipulating the hydraulic variables, pressure and flow. The input variables to the control element are usually in the form of mechanical, pneumatic, hydraulic or electrical signals. In modern proportional hydraulic control devices the input variable is most likely to be a low-power electrical analogue or digital signal, the former providing infinitely variable, the latter discrete control of either flow or pressure.
