3. Installation and Operation

Description

Flowserve CEA actuators are reversible electric rotary valve
actuators. Standard units can provide up to 5000 in-lb of torque and
use a Brushless DC (BLDC) motor and permanently lubricated gear
trains. These actuators are equipped with integral thermal overload
protection with automatic reset and electronically adjustable position
and rotation limit switches. In the event of electrical power failure, all
models feature manual override capabilities.

WARNING: SERIES CEA ACTUATORS ARE

ELECTROMECHANICAL DEVICES SUBJECT TO NORMAL
WEAR AND TEAR. ACTUATOR LIFE DEPENDS 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. AT ELEVATED TEMPERATURES THE DUTY
CYCLE HAS TO BE DERATED, CONSULT FACTORY.

FLOWSERVE ALSO RECOMMENDS THAT THE OPTIONAL
AUXILIARY LIMIT SWITCHES BE USED FOR MONITORING
AND/OR ELECTRICAL INTERLOCK.

a

CAUTION: If necessary, Flowserve recommends indoor, controlled

temperature storage of all products prior to installation. Do not
store product in areas with 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. Do
not store within 50 feet of any source of ozone.

a

CAUTION: FOR WIRING OF ACTUATOR, INCLUDING OPTIONS,

PLEASE REFER TO WIRING DIAGRAM(S) LOCATED INSIDE OF
ACTUATOR TERMINAL BLOCK COVER. Wiring diagrams are also
included in this manual on pages 6 and 7 for reference.

a

CAUTION: The gear train compartment is oil filled. High perfor-

mance Mobil 1 oil is used for standard temperature requirements.
The compartment volume is 12oz. Oil replacement is not required
under normal operating conditions.

3.1 Installation – Flowserve Automax Valve Products

1. Attach mounting bracket to actuator using the four (4) screws and

lockwashers provided in the mounting kit, and tighten securely.
For small size, top mount style valves, attach bracket so the
bracket nameplate will be to the side of the valve.

2. Attach bracket/actuator assembly to valve as follows:

NOTE: If cross-line mounting of actuator is desired, note the
following: Mount the actuator with conduit hole perpendicular to

the flow axis (center line) of the valve and reverse the open/close
decals.

For diverter and three-way valves with V1 porting, and CPT valves,
also see Electrical Installation and Adjustment Section for cam and
limit switch adjustments to facilitate cross-line mounting operation.

a

CAUTION: Ball valves can trap pressurized media in the cavity.

If the valve is or has been in operation and it is necessary to re-
move any valve body bolts, stem nuts, or the valve from the line,
make sure there is NO pressure to or in the valve and operate the
valve one full cycle before and after removal.

Valve Models Top Mount 44 (1/4”–2”), 45 (2.5”–6”), 51/52 (1/2”–
10”), 151/301 (3”–6”), Top Mount 59 (1/4”–4”), WK70/WK74 and
H71 (1/2”–2”), 818/828 (2”–8”), 82/83 (1/2”–10”) and 94 (1/2”–6”):

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

3. Close valve:

• For valves 1/4”–2”, the valve is closed when flats on valve stem

are perpendicular to the line of flow.

• For valves 3” and larger, where the valve stem is square, the

indicator line on top of stem will be perpendicular to the line of
flow or check ball position for closure.

• If any valve information is marked on stop plate or handle, it

will be necessary to transfer this information to the bracket
nameplate.

For 1/4”–2” 44 and 1/2”–2” WK70/WK74, 1/4”–1 1/2” 59 and 1/2”–2”
H71 Series top mount style valves and 1/2”–2” 51/52, 1/2”–1 1/2”
82/83 Series valves with high cycle stem packing as standard:

4. Remove handle nut, lockwasher, handle, separate stop plate (if

any), retaining nut and stop pin(s).

5. Add the two additional Belleville washers with their larger diame-

ter sides touching each other.

6. Add the self-locking nut to the stem and tighten while holding the

stem flats with wrench.

7. Tighten until Belleville washers are flat, the nut will “bottom”, and

then back nut off 1/3 turn. The two additional Belleville washers
and the self-locking nut are included in the mounting kit.

a

CAUTION: The self-locking stem nut is difficult to tighten and

must fully flatten Belleville washers before backing off the nut by
one third of a turn.

For 2” 59, H71, 82/83, and 2.5” 45, 82/83 Series valves and valves
3” and larger with square stem, remove handle assembly (if any),
retaining nut, stop and stop screws.

Replace with valve stem spacer or, if valve has graphite stem packing,
