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.
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.
3 INSTALLATION
NOTE: The Series F39 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.
Sizes 10-35 Rev. R7 actuators may come with an ISO
locating ring, used for optional ISO mounting.
Size 40-50 Rev. R7 actuators have an integral ISO loca-
tion ring.
3.1 Determine mode of operation desired (normally open or
normally closed) of the valve.
3.2 Determine desired quadrant for bracket attachment and
direction of mounting of actuator (in-line or cross-line).
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 pres-
sure 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: 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.
