Direction Control Valve
The direction control valve is located on the right
side of the press frame.
The valve has 4 lever (A) positions labeled Fast
2, Slow 1, Stop 0, and Back R.

Stop 0 position: When the lever has not been
operated, the valve will always return to this
position. There is no movement of the piston.

Back R position: When the lever is pushed
inwards, the piston will raise. As long as the
valve is operated, the piston will move until it
is fully retracted. When the lever is released,
it will return to the stop 0 position and the
piston will stop and stay in the current
position.

Slow 1 position: When the lever is pulled
outwards to the first position, the piston will
extend
at the working speed of .20”/sec (5mm/sec). As long
as the valve is held in this position, the piston will move
downward. When the lever is released, the piston will stop
and stay in this position. The lever will return to the stop
position. This positon will develop full pressure and should
be used during the actual pressing process.

Fast 2 position: When the lever is pulled outwards to the
second position, the piston will extend at the advancing
speed of .31”/sec (8mm/sec). As long as the valve is held in
this position, the piston will move. When the lever is
released, the piston will stop and stay in this position. The
lever will return to the stop position. This positon is for
advancing the ram to the material to be pressed. When the
ram is within .75” (19-20mm) the lever should be moved
back to the Slow 1 position to complete the operation.
Pressure Gauge
The pressure gauge is located in the head of the press. The gauge gives the pressure in PSI
and BAR. The maximum pressure for this press is 3814psi. (263 bar).
If this maximum pressure is reached, also the maximum capacity of the press is reached.
