Speed Valve (MDP 35/50/90)
The speed valve allows the jaws to shift into high speed when not under a load. Two valve spools control this speed
change, the Main Spool Adjustment Screw and the Pilot Valve Adjustment Screw.
Testing the Speed Valve
Close the jaws and observe the movement. If the speed valve is working properly, the jaw closing speed will increase
after 1-2 inches of movement.
Adjusting the Speed Valve
If the jaw movement doesn’t shift to high speed when CLOSING, adjust the pilot valve adjustment screw clockwise until
the jaws shift speed.
