Check to see that the cylinder fully opens and closes
the internal valve without sticking. A build-up of mud,
corrosion, or foreign material could prevent the cylinder
from closing, jamming the internal valve open. Do not
permit this condition to occur.
4. All operating controls should be regularly
inspected and cleaned and oiled. Periodic
lubrication of the operating lever/clevis pivot
is recommended.
5. The Type P631 actuator comes standard with a cover5. The Type P631 actuator comes standard with a cover
to protect the internal parts (air bellows, spring, and
other parts) from the elements and fouling. This also
protects the operator from moving parts. This can
be periodically removed in order to clean and inspect
the mechanism. After inspection, it is important to
replace this cover BEFORE repressurizing and
operating the unit.
