Acceptable Manufacturers (12-Inch Valve and Larger): Limitorque HBC
or EIM WD Series.
Each V510 valve shall be equipped with an electric motor-operated actuator
designed to develop sufficient operating torque to unseat, open and close the
valve under all operating conditions specified herein. Except as modified or
supplemented herein, the actuator shall meet the requirements of AWWA C540.
Each electric motor-operated actuator shall be designed to move the valve from
fully open to fully closed position within the time specified, under the maximum
differential pressure across the valve and maximum flow conditions. The
actuator travel time from fully open to fully closed shall be determined by the
valve manufacturer using pump station and pipeline data to prevent surge for the
project hydraulic conditions.
The valve electric actuator shall be a completely integrated, electrically powered
unit with isolated manual handwheel operation in case of power failure. Provide
motor actuator with rated output torque at least 1.5 times the maximum torque
required to open or close the valve at any position including seating and
unseating conditions.
The actuator shall include the motor, actuator unit gearing, motorized adaptor,
limit switches, torque switches, declutch lever, manual operating handwheel,
local valve position indicator, position transducer, and push button control station
to allow local electric control of valve position.
The actuator shall be suitable for modulating service and Class I duty cycle, shall
be suitable for operation over a temperature range of -20°F to 150°F and shall be
of totally enclosed, non-ventilated construction, meeting NEMA Type 6 enclosure
requirements, at a minimum of 20 feet submersion for 72 hours according to
NEMA standards.
The complete actuator shall be furnished fully factory wired, tested, and ready
for interconnection with the electric power source and external remote control
"dry-contact" interposing relays furnished by others.
All gearing shall be grease or oil-bath lubricated. Lubricating oil shall be food
grade. Ball or tapered roller bearings shall be used throughout.
A handwheel shall be provided for manual operation with an arrow to indicate the
"Open" rotation. The handwheel shall not rotate during electric motor operation
and operation of the handwheel shall not cause the motor to rotate. When in
manual operation, the operator shall remain in this mode until the electric motor
is energized, at which time the actuator shall automatically return to electric
motor operation and shall remain in motor operation until manual operation is
again re-engaged. The change from electric motor to manual operation shall be
accomplished by a positive action declutching lever, which mechanically
disengages the motor and motor gearing. The declutching lever shall be
lockable with a standard padlock. A blocked or fused motor shall not prevent
manual operation. It shall be impossible to place the operator directly into
manual operation while the motor is running. The handwheel shall rotate in a
counter-clockwise direction to close the valve. The handwheel diameter shall be

Reliability engineered: The UPS shall have a dual-track redundant
configuration that utilizes either line or inverter source for power and
shall be designed to meet or exceed an expected MTBF of at least
150,000 hours per proven field service.
