While looking in the bore,
open
and

the valve.
Note:
If a choice is available, the valves should be installed with the flow of the
media from the end piece to the body.
Note:
The MOGAS Watson Series valve operates
counter-clockwise to open,
clockwise to close
.
VERIFY OPERATING POSITION
Verify that the ball
open
/
closed
position matches the
handlever or actuator
open
/
closed
position indicators.
Watson Series Valves are bi-directional valves and
may be installed in either direction.
Note:
Larger valves may require the actuator to be in place to rotate the ball.
Note:
Valve item numbers shown in
bold
correspond with items shown in the
Valve Item Reference Number
section (pages 4 – 5) of this document.
CAUTION!
The actuator, if supplied, must not be re-oriented
without removal from the valve. This prevents 180°
rotation of the ball and assures the mate-lapped
ball and seat surfaces match. (Seat leakage may
occur when the ball and seat surfaces are not
matched per the engineered design.)
THIS WILL AFFECT THE VALVE WARRANTY.
!
CAUTION!
All welding / grinding debris must be thoroughly
flushed from all associated piping before valve is
installed.
THIS WILL AFFECT THE VALVE WARRANTY.
