Screw - in Cartridge Throttle
Valves
Throttle valve VSV2 is used to control
the flow in a hydraulic system in one or
both directions.
1) A higher sensitivity control is
achieved by using the M12x1
screw thread
2) After loosening the lock nut the
valve may be screwed out only up
to the red marked safety notch;
otherwise the valve could get
completely unscrewed leading to
working fluid escape.
