›› Wide range of flow rate options
›› Adjustable by allen key or hand screw, optionally sealable (lockwire holes)
›› In the standard version, the valve is zinc-coated for 240 h protection acc. to ISO 9227

Functional Description

This pressure compensated, hydraulic flow regulator in the form of a screw-in cartridge with fixed orifice and
variable spring setting is designed to control flow rates independently of pressure and temperature, especially
in systems where only small movements due to load changes are required. The flow rate stabilization is
provided by a pressure compensator in the direction from 1 to 2. The valve will maintain the set flow regardless
of pressure variations on the regulated or inlet port.
In flow direction 2 - 1, the valve works as an ordinary throttle valve without pressure compensation. The
regulated flow increases with clockwise rotation of the adjustment screw and descreases with
counter-clockwise rotation. The desired settings can be locked down.
