Ensure the precoat and effluent valves
are closed.
Valves with
Pneumatic
Actuators
Actuator is not
operating.
No air is getting to or
from the actuator.
Check system air pressure. Confirm at
80-90 PSI.
Check air line tubing is properly
attached.
Check for leaks in the air lines and
fittings.
Air flow is restricted due
to needle valves being
closed.
Confirm the needle valves are open to
allow air flow and are properly adjusted.
Actuator is moving
too quickly or slowly.
Air flow needs to be
adjusted at the needle
valves on the actuator.
Turn knobs counterclockwise to
increase actuator speed. Turn knobs
clockwise to decrease actuator speed.
Valve disk is sticking
closed and then
slamming open.
Valve stops are out of
adjustment.
Adjust the actuator limit stops so that
