For use in meter-in, meter-out

and bleed-off applications

Pressure compensated flow control valves are installed

in hydraulic systems where only small speed or

revolution variation due to load changing are required.

The valve consists of throttling orifice (1), pressure

compensator (2), bushing (3), adjustment screw (4) and

spring (5).

Throttling in direction 1 ® 2 is realised on the throttling

orifice. The flow rate depends on the orifice diameter

and on the pressure difference at the orifice. The

pressure difference can be adjusted in a certain range

through preloading the spring (5), which results in the

respective flow change. The allocation of the orifice

diameters and the corresponding flow rates is apparent

from the characteristics. The flow rate adjustment can

be accomplished by adjustment screw (4). The

clockwise rotation increases the flow rate, the

anticlockwise rotation decreases the flow rate.

The flow rate stabilization is provided by pressure

compensator (2), which is situated behind the throttling

orifice and mounted into bushing (3). The pressure

compensator continuously compares the pressure

difference at the throttling orifice (1) with the value given

by the spring preload.

In flow direction 2 ® 1, the valve works as an ordinary

throttle valve withouth pressure compensation feature.

The pressure losses depend on the orifice diameter –

see the respective characteristics.

The valve housing (7), the nut (6) and the adjustment

screw (4) are zinc coated.
