They are designed as slot-type throttles (complete stroke) and are therefore impervious to micro-contaminants (no edge filter effect).
The precision throttle valves type FG are preferentially used for adjusting the switching time of directional valves, preventing pressure surges and damping oscillations. The throttle effect is achieved via the effective thread length.
The settings can only be adjusted using tools.
