DESCRIPTION

Worcester Controls/McCANNA ACCESS I and M Series 39 actuators
are pneumatic quarter-turn valve actuators. The solenoid and limit
switches for the ACCESS I are integral to the actuator end cap, while
the ACCESS M is a separate factory-mounted enclosure containing
the solenoid and limit switches. The design utilizes a double-rack,
single-pinion concept, with each rack integrally cast to a piston. Both
pistons are supported and centered by large, stainless steel guide
rods. In double-acting units, both pistons are pressurized on both
strokes of the actuator. Ambient temperature range of ACCESS unit is
0°F minimum to 160°F maximum.

Standard units feature an extended top shaft for manual override
capabilities and a completely modular design which allows simple
attachment of a variety of accessories. The units feature a control
block (with spool valve) which properly directs supply air to the
actuator. The control block provides independently adjustable speed
control for both opening and closing strokes of the actuator on
double-acting units, and for the closing stroke on spring-return units
(standard mounting configuration). The units can also be supplied
with an air connection block (in place of control block) for when there
is no solenoid valve integral with unit.

a WARNING: SERIES 39 ACTUATORS ARE ELECTRO-MECHANICAL
DEVICES SUBJECT TO NORMAL WEAR AND TEAR. ACTUATOR LIFE IS
DEPENDENT UPON APPLICATION AND ENVIRONMENTAL
CONDITIONS. IF APPLIED IN HAZARDOUS SERVICES, SUCH AS BUT
NOT LIMITED TO MEDIA TEMPERATURE EXTREMES, TOXINS,
FLAMMABLES, OR OTHER SERVICES WHERE IMPROPER OR
INCOMPLETE OPERATION COULD PRODUCE A SAFETY HAZARD, IT IS
INCUMBENT UPON THE SYSTEM DESIGNER AND THE USER TO
PROVIDE PROPER WARNING DEVICES SUCH AS TEMPERATURE
SENSORS, OXYGEN SENSORS AND FLOW SENSORS. FLOWSERVE
ALSO RECOMMENDS THAT THE INTEGRAL LIMIT SWITCHES BE USED
FOR MONITORING AND/OR ELECTRICAL INTERLOCK.

CAUTIONS: When actuator is installed in outdoor conditions, water
can enter the exhaust hole(s) of the control block or air connection
blocks, and then freeze. Flowserve suggests a cover be used, or
mount the actuator such that the block exhaust hole(s) will not fill
with water.

Flowserve recommends that all products which must be stored
prior to installation be stored indoors, in an environment suitable
for human occupancy. Do not store product in areas where
exposure to relative humidity above 85%, acid or alkali fumes,
radia tion above normal background, ultraviolet light, or
temperatures above 120°F or below 40°F may occur. Do not store
within 50 feet of any source of ozone.

IMPORTANT: INCLUDED IN ALL 39 ACTUATOR ACCESSORY AND
REPAIR KITS IS A REBUILD/ACCESSORY ADDITION LABEL, WHICH
IS TO BE MARKED WITH A PERMANENT MARKER AND THEN
APPLIED TO THE ACTUATOR AFTER AN ACCESSORY KIT HAS BEEN
INSTALLED OR AN ACTUATOR HAS BEEN REPAIRED.

All ACCESS M units have four threaded tamper proof plugs installed
over the enclosure mounting machine screws. No attempt should be
made to remove these plugs. If it becomes necessary to remove
enclosure from actuator end cap, consult Flowserve.

INSTALLATION

NOTE: The Series 39 actuator is normally installed with its major axis
parallel to the pipe line (this is mandatory when mounting actuator to
90° V1 diverter/three-way (D44 & T44) valves and CPT valves. The
actuator can be oriented above, beside or beneath the valve without
affecting its operation.

Sizes 10–35 Rev. R6 actuators may come with an ISO locating ring
used for optional ISO mounting.

A. Determine mode of operation desired (normally open or normally

closed) of the valve.

B. Determine desired quadrant for bracket attachment and direction

of mounting of actuator (in-line or cross-line).

C. Attach mounting bracket to actuator using four (4) cap screws

and lockwashers provided in mounting kit. To avoid any damage
to the Series 39 actuator body, ONLY the proper length screws
supplied with the mounting kit should be used. For

will be to side of valve.

For mounting to 818/828 Series valves insert ISO locating ring
into groove on bottom of actuator before attaching to bracket.
