Function he integrated electronics (OE) compares command and actual values and the solenoids of the pilot control valve are actuated with a proportional current according to the control deviation. he pilot control valve takes a proportionally controlled position and controls the flow in and out of the control chambers (7) and () that actuate the main spool (5) through the closed valve control loop up to control deviation. his means that the stroke of the main spool is regulated proportionally to the command value. It must be noted that the flow also depends on the valve pressure drop. Valve particularities he flow can pass through the valve from to or from to. he seat piston closes or opens at 5% of the command value. t lower command values, the valve control loop attempts to guide the piston and thus presses it onto the seat at full pilot pressure and blocks the connection in a leak-free way. he specified valve dynamics only apply to the control area of the valve. t command value steps from the seat to lower opening values, additional delay times occur. he opening point of 5% (=.5 V or.5 m) is set at the factory. Due to the internal setting of the pilot control valve, the pilot pressure is connected to control chamber () in case of a power failure, i.e. the main stage is closed. he control electronics feature an offset setting to compensate pilot trimming. Due to differences in diameter in the seat range, the pistons are statically not pressure-compensated. o compensate the force differential, 6%/22% of the system pressure at piston S...L/S...R is required as pilot pressure. With reserves for flow force and dynamics, this defines the recommended minimum pilot pressure x 7 "" 1) Zero F E C D 1) 1) referably, port is to be connected to the actuator.
