BRAY Series 70 Electric Actuator
Operation and Maintenance Manual

SPinner
A spinner is available to ease and speed the manual override
of the Bray Series 70 actuator. The Housing Size 6 units
mount the spinner on a lever which screws onto the back of
the handwheel. The Housing Size 12-180 units mount the
spinner on the rim of the handwheel. Note that care should
be exercised in the use of spinner equipped handwheels.
Rapid operation of the handwheel to close the valve may
cause water hammer. Also, rapid travel into a travel stop
may cause damage.

Bray’s local control station gives the user the ability to locally
override the actuator electrically. The station is open / stop /
close operation in the local control mode. Red and green end
of travel indication lights are also provided. Depending on
how it is wired the control station
can be used on the on - off
units and the servo controlled modulating units. Optional
key operated locking switches are available.
Note: The control station used with On - Off S70 and that
used with modulating S70 have different contact blocks
internally, the correct part number must be used to ensure
you order the correct unit (see price sheet).
