STEP 13
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 opening is too slow, turn the adjustment screw OUT,
counterclockwise, increasing the rate of closing.
STEP 14
Opening Speed Flow Control Adjustment: The Opening speed
flow control allows free flow into the cover and restricted flow out
of the cover of the main valve.
If valve opening is too slow, turn the adjustment screw OUT, coun-
terclockwise, increasing the rate of opening (See Figure 4B).
If valve opening is too quick, turn the adjustment screw IN, clock-
wise, decreasing the rate of opening (See Figure 4A).
