MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
AUTOMATIC ACTUATED BUTTERFLYVALVES. (MODEL ROWPU-1 ONLY)
An automatic actuated valve is suspected of leaking (letting water or cleaning solution through when it is closed).
Clean/flush tank overflows or clean/flush tank drops in level until no solution is left.
CAUTION
Make this adjustment only when the valve to be adjusted is in its closed operating position. Making this
adjustment when the ROWPU automatic control system signals the valve actuator to open will cause the
valve to work backwards (valve open when it should be closed or closed when it should be open).
Check valve adjustment.
Push valve position Indicator toward the closed position. If the valve cannot be
placed into closed position or continues to remain in the open position, replace
valve (para. 4-47).
