Flowserve 36 Series Electric Actuator - Manual

Worcester Actuation Systems
This manual includes instructions for extra limit switch and auto
sequence timer options.
DESCRIPTION
Flowserve Worcester Actuation Systems Series 36 Electric Actuators
are unidirectional rotary valve actuators. Standard units can provide
up to 550 in-lb of torque delivered at the output shaft. The AC
versions of these actuators use rugged shaded-pole motors with
integral thermal overload protection and automatic reset. An internal
adjustable limit switch is used for accurate control. One additional
limit switch (optional) can be mounted within the unit for remote
position indication or the control of an auxiliary piece of equipment.
IMPORTANT: The Series 36 Actuator is a unidirectional, 90° actuator,
and therefore cannot be used on butterfly valves, ball valves with an
upstream relief hole (cryogenic, chlorine, etc.), or on diverter/three-
way valves (the series 75 is required for these). The actuator must be
mounted above the valve, with the output shaft and valve stem
vertical. It will not function if mounted at an angle, or below the valve.
a WARNING: Series 36 Actuators are electromechanical devices
subject to normal wear and tear. Actuator life is dependent upon
application and environmental conditions. If used 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 optional auxiliary limit switches be used for
monitoring and/or electrical interlock.
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.
I. INSTALLATION
A. Attach mounting bracket to actuator using four (4) cap screws
and lockwashers, and tighten securely. For small size top-mount
style valves, attach bracket such that bracket nameplate will be to
side of valve.
B. Attach actuator/bracket assembly to valve as follows:
CAUTION: Ball valves can trap pressurized media in the internal
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. Close valve (valve is closed when flats on stem are
perpendicular to the line of flow). If any valve information
is marked on stop plate or handle, it will be necessary to
transfer this information to the bracket nameplate.
