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

4"– 2" top-

mount style valves, attach bracket such that bracket nameplate

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.
