CMA actuator castings are manufactured from aluminium
alloy with stainless steel fasteners. The user must ensure that
the operating environment and any materials surrounding the
actuator cannot lead to a reduction in the safe use of, or the
protection afforded by the actuator. Where appropriate the
user must ensure the actuator is suitably protected against its
operating environment.

The handwheel is located on
the top cover of the CMA (All
Variants). Push and hold the
hand wheel down and rotate
to extend/retract or rotate the
actuator output drive.
verify direction of output shaft rotation for clockwise

note that under no circumstances should any
additional lever device such as a wheel key or wrench
be applied to the hand-wheel in order to develop more
force when closing or opening the valve as this may
cause damage to the valve and/or actuator. It may also
cause the valve to become stuck in the seated or back
seated position.
