The following table identifies the valves shown in the above diagram:
Valves #4 and #8 are the pressure building valves for Tank #1 and Tank #2 respectfully.
These valves are not on the panel, but are mounted on the top of the pressure building coil next
to the respective Laser-Cyl.

ALVES
The solenoid valves that are used in this system have very long life and valve failure or
replacement is highly unlikely. In the unlikely event that a valve needs to be repaired, the
following table gives the part number of the valve. It is generally not necessary to remove the
valve body, but only replace the top works of the valve. When replacing or inspecting the piston
assembly, 4 bolts are removed holding the top head works to the body of the valve. It is very
important upon replacement of the top head works to replace the gasket and take special
precautions to torque the bolts evenly to 10 to 12 ft. per pound. Over torquing will distort the
casting and cause the piston assembly to hang up.
