The pilot control valve (7) takes a proportionally controlled position and controls the flows that actuate the control spool (2) through the closed valve control loop up to zero control deviation. This means that the stroke of the control spool (2) is regulated proportionally to the command value. It must be noted that the flow also depends on the valve pressure drop. Valve features The flow can pass through the valve from A to B or from B to A. The control spool (2) closes or opens at 5 % of the command value. At lower command values, the valve control loop attempts to guide the control spool (2), thus presses it onto the seat at full pilot pressure and blocks the connection in a leakage-free way. The specified valve dynamics only apply to the control area of the valve. At command value steps from the seat to lower opening values, additional delay times occur. The opening point of 5 % (= 0.5 V or 4.8 mA) is set at the factory. The pilot control valve (7) is designed as bi-directionally controlled longitudinal spool valve with double stroke solenoid and control sleeve and has a mechanical trimming in case of power failure. The integrated electronics (5) regulates the position of the control spools of main and pilot control stage and offers either the analog interfaces “A1” and “F1” or the full bus functionality with interface “D9”. Damping plate "D" The damping plate (6) reduces the acceleration amplitudes on the on-board electronics (frequencies >300 Hz). Notice: Use of the damping plate is not recommended for applications with mainly low-frequency excitation IndraWorks DS PC program To implement the project planning task and for the parameterization, the user may use the IndraWorks DS engineering tool (see “Ac
