FEATURES & BENEFITS
• No water spillage around the press during
mold changes for personnel safety.
• Makes mold changes quick, clean & safe.
• Increases mold life by preventing rust deposits

Regarding Galvanic Corrosion
It is strongly recommended that a Dielectric Fitting (see
Manual Vent
(10-32 F thread) Accessories and Parts) is purchased for use with this valve
when copper or brass piping is present in the water circulating
lines. Galvanic corrosion can occur in the presence of:
• more noble metals
Optional • electrolytic connection

Bracket • elevated water temperatures.

surface using the two supplied angle brackets. Line TYPICAL INSTALLATION SCHEMATIC
mounting of the valve to rigid pipe is not recommended.
The brackets are preinstalled at the base of the unit, but
may be moved to either end of the valve body for alternate
mounting positions. If brackets are located at the valve
body end, be sure there is adequate clearance to move
the selector handle.
A check valve (supplied) should be installed in the return
line, downstream from the return manifold. The check valve
will prevent fluids from backing into the mold after purging.
Attach the incoming water supply to the “Water Inlet”.
Attach shop air to the 3/8” NPT “Air Inlet”, attach the “Air/
Water Outlet” to the supply manifold. Vented air escapes
from the “Manual Vent” via a 10-32 threaded opening,
which can be connected to a drain tube to route residual
moisture and vent air away from the floor.
