Twin Power
Pneumatic Multiturn actuator in Standard and ATEX design
MOUNTING
The Twin Power actuator works beyond reproach in
all positions. Valves with fluid media should if
possible be fitted in such a way that fluid leakage
from the packing box is not led from the packing box,
through the stem, into the stem nut and the actuator.
It is desirable that the valve stem should be
assembled in an upright position. If this cannot be
done care should be taken to tighten the gland
regularly and change the box packing when
necessary.
Grease the drive bush carefully and ensure that
there is no radial or axial diffraction between the
drive bush and hub. Check that the numbers of turns
not exceed the permitted turns on the chosen
indicating bridge
The last three numbers in the type denomination
inside the actuator cover, specifies the type of
Indicator Bridge

100

050S
In cases where the Twin Power actuator will be
assembled on valves with rising stem and rising
handwheel, the length of the hub must be minimum
the length of the drive bush axially movement.
Some practical advice
Ensure that the 3/8" air connections are positioned
so as to prevent dirt and liquids entering the motor.
If necessary, a short length of pipe should be fitted
into each port, with the end pointing downwards.

ASSEMBLY EXAMPLE
Valve designed with rising stem and handwheel.
Instead of the handwheel a driving bush with keys is
fitted on the stem end. The driving bush rises axially
corresponding to the valve rise. In this case an actuator
must be chosen with a hub length corresponding to the
rise of the bush.
Valve with rising stem and non rising handwheel.
A flange is mounted on the valve, and a driving bush
with keys fitted in the place of the hand-wheel for
transmission of the turning movement to the stem unit.
