Flowserve 10 ACCESS I 39 Actuators - Manual

Worcester Controls
DESCRIPTION
Worcester Controls/McCANNA Access I Series 39 actuators are
pneumatic quarter-turn valve actuators with solenoid and limit
switches integral to the actuator end cap. 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 the
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 that allows simple
attachment of a variety of accessories. The units feature a control
block (with spool valve) that 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 electromechanical 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
block, 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 that 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, radiation 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.
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 and T44) valves and CPT valves. The
actuator can be oriented above, beside or beneath the valve without
affecting its operation.
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
Z\v" - 2" top
mount style valves, attach bracket such that bracket nameplate
will be to side of valve.
