Actuator Installation Notes
These notes apply to the installation of Bray S92/93 pneumatic valve actuators.
 Verify that the valve and the actuator are both in the same
position (both open or both closed) before mounting the
actuator to the valve.
 Apply a light coating of grease to the inside of the actuator
output bore before installing the actuator on the valve. This
will allow the actuator to be more easily removed from the
valve stem even after years of service.

bore to the valve stem, apply a light coating of grease to
the inside of the stem adapter as well as the inside of the
actuator output bore.
 Some stem adapters are kits consisting of multiple
components. These kits may contain spacers that look
like stem adapters, but are designed to keep the stem
adapter in place during operation of the actuator. Verify
that all stem adapters and spacers are installed in the
