2 Way Proportional Flow Control Valve

Characteristics
Proportional flow control valves of the series DUR*L06
are used to generate pressure-compensated flow from
A to B. The valve is equipped with a built-in check valve
for the return flow.
For meter-in and meter-out control of an actuator a recti-
fier plate can be used.
Function
When solenoid current is applied, the metering spool
opens against the reset spring and the flow is regulated
by the pressure compensating spool to port B.
With the aid of the pressure compensating spool, the
pressure drop is held constant on the metering window.
Thus pressure load changes are compensated, and the
oil flow remains constant.
In combination with the digital electronic module PC-
D00A-400 the valve parameters can be saved changed
and duplicated.

Sandwich rectifier plate
If a 2 way flow control valve is used in combination with
a rectifier plate the valve can be used for meter-in and
meter-out flow control of an actuator.
Design
The intermediate rectifier plate is designed with 4 identi-
cal, symmetrically arranged check valves. Thus the dif-
ferential pressure is the same in both flow directions.
