Operation and Maintenance Manual Model 7AA Wafer Grinder

COOLING WATER FLOW VALVE
A brass globe valve located on the rear cabinet controls the
flow of cooling water through the grind spindle motor cooling
jacket. As mentioned previously a flow switch is installed in the
line to check for sufficient (0.25 GPM) water flow. The globe
valve should be opened just enough to allow for continuous flow
above the minimum flow requirement without excessive water
consumption.
