Step 5
Closing Speed Needle Valve Adjustment: The closing speed
needle valve regulates fluid pressure into the main valve cover
chamber, controlling the valve closing speed. If valve closing is too
slow, turn the adjustment screw OUT, counterclockwise, increas-
ing the rate of closing.
(If Installed) Opening Speed Flow Control Adjustment: The
Opening speed needle valve restricts flow out of the cover of the
main valve.
If the main valve is opening too slowly turn the adjustment screw
OUT, counterclockwise, increasing the rate of opening (See Figure
2B).
If the main valve is opening too quickly, turn the adjustment screw
IN, clockwise, decreasing the rate of opening (See Figure 2A).
