GENERAL INFORMATION
Introduction
NOTICE
Failure to follow these procedures and observe these notes
cautions and warnings including the use of non-OEM parts
could lead to hazards andor void product warranties either
expressed or implied
The design features of this valve include a three piece
construction allowing ease of maintenance without special tools
These valves feature a “free floating” ball The ball is not fixed
but is free to move with the line pressure As a result of this
feature these valves are capable of tight shut-o with flow in
either direction regardless of the position of the valve in the line
The downstream seat opposite the pressurized side of a closed
valve must carry the load exerted by the line pressure on the ball
while the upstream seat is subject to little load or wear Turning
the valve end-for-end in the pipeline will increase useful seat life
by dividing seat wear between the two seats
The valve should be maintained as part of a preventative
maintenance program and in accordance with Bray’s
recommended pressure and temperature to ensure a long service
life During shipment storage and in operation the valve should
be fully open or fully closed (“open” is preferred for shipping and
storage)
