Flowserve 72 Series Electri-SAFE - Manual

Worcester Controls
Worcester Controls Series 72 actuators are electro-hydraulic quarter-
turn valve actuators. 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.
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 feature a normally
open solenoid valve which returns the actuator to its initial position
when power is lost to the actuator.
a WARNING: Series 72 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.
CAUTION: 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.
INSTALLATION
NOTE: The Series 72 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.
Actuators 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 72 actuator body, ONLY the proper length screws
supplied with the mounting kit should be used. For small 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. Note: Ring can be permanently held in
groove by applying Loctite to ring before inserting in groove.
D. Attach bracket/actuator assembly to valve as follows:
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.

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.
a. 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.
