1 SAFETY
The safety terms DANGER, WARNING, CAUTION and
NOTE are used in these instructions to highlight partic-
ular dangers and/or to provide additional information on
aspects that may not be readily apparent.
DANGER: indicates that death, severe personal injury and / or
substantial property damage will occur if proper precautions
are not taken.
WARNING: indicates that death, severe personal injury
and / or substantial property damage can occur if proper
precautions are not taken.
CAUTION: indicates that minor personal injury and / or
property damage can occur if proper precautions are not
taken.
NOTE: indicates and provides additional technical infor-
mation, which may not be very obvious even to qualified
personnel. Compliance with other, not particularly empha-
sised notes, with regard to transport, assembly, operation
and maintenance and with regard to technical documentation
(e.g. in the operating instruction, product documentation or
on the product itself) is essential, in order to avoid mistakes,
which, in themselves, might directly or indirectly cause
severe personal injury or property damage.

2 DESCRIPTION
Worcester Controls/McCANNA Series F39 actuators
are pneumatic quarter-turn valve actuators. The design
utilizes a double-rack, single pinion concept, with each
rack integrally cast to a piston. On sizes 10-50, both
pistons are supported and centered by large, stainless
steel guide rods that are also used to control the rotation
of actuator via externally mounted stroke adjustment
screws. In double-acting units, both pistons are pressur-
ized on both strokes of the actuator.
Standard units feature an extended top shaft for manual
override capabilities and a completely modular design
which allows simple attachment of a variety of accesso-
ries. All units allow the direct mounting a solenoid control
block which properly directs supply air to the actuator.
On double-acting actuators, the solenoid control block
provides independently adjustable speed control for both
opening and closing strokes of the actuator. On spring-re-
turn actuators only the spring stroke is adjustable.
WARNING: series F39 actuators are electro-mechanical
devices subject to normal wear and tear. Actuator life is
dependent upon application and environmental condi-
tions. If applied in hazardous services such as, but not
limited to, media temperature extremes, toxins, flamma-
