DESCRIPTION APPLICATION
Pilot operated, load-compensated proportional flow control poppet These valves are used in hydraulic systems, in which the positio-
valve as screw-in cartridge for cavity according to ISO 7789. When ning of loads and the simultaneous controlling of the lowering of
the solenoid is deenergised, the control spool closes practically these loads are demanded. The insensitivity to load changes and
leakage-free. With increasing solenoid current, the volume flow the very small leakage are a great advantage for this purpose. They
from the inlet port (2) to the regulated outlet port (1) increases al- are ideally used in the bypass to the pump. The screw-in cartridge
most independently of the load pressure. For the control, Wandfluh is perfectly suitable for installation in control blocks. For machining
proportional amplifiers are available (see register 1.13). the cartridge cavity in steel and aluminum blocks, cavity tools are

available (hire or purchase). Please refer to the data sheets in
register 2.13.
