Product Description
The valve types DRE and ZDRE are electrically pilot-operated 3-way pressure reducing valves with pressure limitation of the actuator. They are used for reducing a system pressure.The valve basically consists of a pilot control valve (1),proportional solenoid (2), main valve (3) with
main control spool (4).Type DRE Command value-dependent setting of the pressure to be reduced in channel A via the proportional solenoid (2).
In the depressurized port P, the spring (17) holds the main control spool (4) in the initial position.Thus, opening the connection from A to T and blocking of the connection from P to A.Pressure connection from port P to the ring channel (5).Pilot oil flows from the bore (6) to port T, via the flow
controller (7), the nozzle (8) to the pilot control valve (1), the throttle gap (9) to the longitudinal groove (10) and the bores (11, 12).
Pressure reduction – Build-up of the pilot pressure in the control chamber (16) as function of the command value.Movement of the main control spool (4) to the right,hydraulic fluid flows from P to A.Actuator pressure pending in port A to the spring chamber (15) via channel (13) and nozzle (14).Increase in the pressure in port A to the set pressure of the pilot control valve (1) leads to the movement of the main control spool (4) to the left. Pressure in port A is almost identical with the set pressure at thepilot control valve (1).Pressure limitation If the pressure in port A exceeds the set pressure of the pilot control valve (1), the main control spool (4) will be moved further to the left.Thus, opening of the connection from A to T and
limitation of the pressure pending in port A to the set command value.
