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 pressur­ized 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 accesso­ries. 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-re­turn actuators only the spring stroke is adjustable.

WARNING:

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, flamma-

bles, 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 optional auxiliary limit switches be used for
monitoring and/or electrical interlock.

CAUTION: When actuator is installed in outdoor
conditions, water can enter the exhaust holes of the
double-acting solenoid block, and then freeze. Flowserve
suggests a cover be used, or mount the actuator such
that the solenoid block is upside down.

Do not install F39S (spring-return) models with air

connection in end cap or with integral solenoid vertical,
without proper precautions to eliminate the ingress of
water spray or rainfall. Exposed end cap or solenoid vent
port will allow water to accumulate in spring chambers.

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, 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.

3.3 Attach mounting bracket to actuator using four (4) cap
screws and lock washers provided in mounting kit. To
avoid any damage to the Series F39 actuator body, ONLY
the proper length screws supplied with the mounting kit
should be used. For small size top mount style valves,
attach bracket such that bracket nameplate will be to side
of valve.

3.4 For mounting to 818/828 Series valves, insert ISO locating
ring into groove on bottom of actuator before attaching
to bracket. Ring can be permanently held in groove by
applying Loctite® 638 to ring before inserting in groove.

NOTE:

Size 05F39, if furnished with factory solenoid, shall
be “cross-line” mounted (i.e. at 90 degrees to the pipe
run) to ensure adequate clearance for air connections.

3.5 Prepare valve for actuation:

CAUTION: Ball valves can trap pressurized media in the

cavity. If it is necessary to remove any valve body bolts,
stem nuts, or remove valve from the line, and if the valve
is or has been in operation, make sure there is NO pres­sure to or in the valve and operate valve one full cycle.

3.5.1 Valve models 45 (2½”–6”), 59 (2”–4”), 51/52 (½”–10”),
151/301 (3”–6”), 82/83 (½”–10”), 818/828 (2”–8”), 94
(½”–6”), 44 (¼”–2”), 59 (¼”–1½”), WK70/WK74 and
H71 (½”–2”):

NOTE:

included in all F39 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.

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

NOTE:

For above listed valves, it is not necessary to
remove any valve body bolts or remove valve from line in
order to mount actuator.

3.5.2 Rotate valve ball and stem to position necessary to
achieve desired operation. If any valve information is
marked on stop plate or handle, it will be necessary to
transfer this information to the bracket nameplate.

3.5.3 For ¼”–2” 44, ½”–2” WK70/WK74, ¼”–1½” 59, and
½”–1½” H71 series top-mount style valves, and ½”–2”
51/52, ½”–1½” 82/83 series valves with high-cycle stem
packing as standard, remove handle nut, lockwasher,
handle, separate stop plate (if any), retaining nut and
stop pin(s). Add the two additional Belleville washers with
their larger diameter sides touching each other. Add the
self-locking nut to the stem and tighten while holding the
stem flats with wrench. Tighten until Belleville washers
are flat — the nut will “bottom” — and then back nut off
1/3 of a turn. The two additional Belleville washers and
the self-locking nut are included in the mounting kit.

CAUTION: Due to the design of the self-locking stem

nut, resistance will be felt as it threads onto the stem
assembly. Ensure the Belleville washers are fully flattened
before backing off.

3.5.4 For 2” 59, H71, 82/83, and 2½” 45, 82/83 valves, and
valves 3” and larger with square stem, remove handle
assembly, retaining nut, stop and stop screws. Replace
with valve stem spacer or, if valve has graphite stem
packing, with two Belleville washers (except 8”,10” 82/83
and 10” 51/52), and replace retaining nut.

NOTE:

Belleville washers are installed with their larger
diameter sides touching each other. Do not use stem
spacer when Belleville washers are used. Using a wrench
to prevent stem from turning, tighten retaining nut until
stem packing is fully compressed or Bellevilles, if used,
are fully flattened, then back off nut 1/6 turn. Excessive
tightening causes higher torque and shorter seal life.

NOTE:

Large valves with V51 high-cycle stem packing
option installed, identified by two Belleville washers
installed and handle assembly, stop and stop screws
removed, and 818/828 series valves, do not require stem
area disassembly.

3.5.5 For 2”–8” 818/828 valves, remove handle assembly,
locking plates and hardware, and stop screw (if any). Do
not remove stop plate (2”–6” sizes) or spacer (8” size).

3.5.6 For ½”–2” 94 valves, remove handle (if any). Do not
remove gland plate or gland bolts.

3.5.7 For 3”–6” 94 and 2”–8” E818/828 valves, remove handle
assembly, stop, and spacer (if any). Do not remove gland
plate or gland bolts.

• Fail Open or Fail Close - The normal method of mounting
is to have the actuator in line with the pipe line and the
valve and actuator in the “FAIL-CLOSED” (Clockwise to
close) position. “FAIL-OPEN” can be achieved using
the method above but the actuator will then work
as Clockwise to open).

• For “FAIL-OPEN” but with Clockwise to close opera­ tion, the pistons in the actuator will need to be removed
and reassembled from the opposite ends of the
actuator (keeping the guide rods the same sides
relative to the body). This will result in a slight offset
of pinion position on some sizes. See below:

3.6 Attach bracket/actuator assembly to valve as follows:

3.6.1 Center coupling on valve stem.

3.6.2 Lower mounting bracket/actuator assembly over coupling
and onto valve, making sure that female star drive actu­ator shaft engages in the correct orientation with the
coupling.

3.6.3 Secure bracket to valve using cap screws and lock­washers, or bolts and nuts provided in mounting kit.
Tighten securely. For small size top-mount style valves,
bracket nameplate will be to side of valve.

3.6.4 Install set screws (if any) in coupling and tighten securely.

3.6.5 Determine if mode of operation (air to open or close/fail
open or closed) is as desired; if not:

• Air to Open or Close - On all sizes of F39 double-acting
and spring-return actuators, the female drive shaft
is a star drive. This allows selection of either mode of
operation by indexing the coupling (including valve ball
and stem) 90° to the actuator shaft, while keeping the
actuator in an in-line orientation.

3.6.6 Determine position indication. Buttons on position indi­cator are set up to show valve closed on in-line mounting,
i.e., pistons together on actuator. If different indication is
required:

• Check which visual indication is required.

• Check that indicator, when located on actuator shaft,
will show correct indication.

• To change indication, on size 10 to 20 push out
(remove) red and white buttons and reassemble in
opposite positions. For sizes 25 and above remove the

complete indicator and orientate to the correct position.

• Locate indicator on actuator shaft flats. Press firmly
until location nibs snap into recess on actuator shaft.

4 AIR SUPPLY AND ELECTRICAL

INSTALLATION

4.1 Air Supply:

The Series F39 Actuator is factory lubricated. For optimum

operation, the use of filtered and lubricated air is recom­mended.

4.2 Air Supply Pressure:

Standard double-acting actuators require 40–120 psig

supply air. Spring-return actuators require 80–120 psig
supply air. Spring-return actuators can also be set up
to operate on supply air pressures ranging from 40–80
psig by using fewer springs. See “Rebuilding Instruc­tions”, Spring-Return Actuator, paragraph 1 on page 13
for proper number and location of springs for reduced
supply air pressures.

WARNING: Air pressure greater than 120 psi must not be

applied.

4.3 Air Supply Connections:

4.3.1 No Integral Solenoid:

Double-Acting (N Models) – Connect air supply lines to

both NPT (1/8” on size 05, ¼” on sizes 10–50) ports.

Spring-Return (SN Models) – Connect air supply line to

the outboard NPT (1/8” on size 05, ¼” on sizes 10–50)
port.

For sizes 10–50, the ports are on the solenoid end cap.

The solenoid end cap is the one on the right end of the
actuator when looking at the nameplate. For 05 size only,
the ports are on the solenoid block interface plate on back
of actuator when looking at the nameplate. For size 05
spring-return it is on the back and near center of actuator.

4.3.2 With Integral Solenoid:

Connect air supply line to the NPT (1/8” on four-way

double-acting blocks, ½” on threeway spring-return
blocks) port on the solenoid block.

4.4 Recommended Tubing Sizes:

In order to provide sufficient flow of supply air to the

Series F39 actuator, the following tubing sizes are recom­mended:

5. Air Consumption

The following chart shows the amount of pressurized (80

psig) air consumed per stroke in cubic feet. To determine
the total amount of air consumed per complete cycle
for double-acting actuators, simply add the volumes for
both the opening and closing strokes together; for spring
return units, the total volume of air consumed is the
volume shown for the opening stroke.
