While looking in the bore, open and close the valve.
Note:
Larger valves may require the operator to be in place to rotate the ball.
CAUTION!
The operator must not be re-oriented without
removal from the valve. Contact MOGAS service.
(Seat leakage may occur when the ball and seat
surfaces are not matched per the engineered
design.)
THIS WILL AFFECT THE VALVE WARRANTY.
The fully open position is the most important position
to set. It is preferred that the open stop be set while
the valve is not installed in the pipeline. This allows
for the bore to be properly aligned, ensuring that no
edges are exposed to the flow.
Note:
The MOGAS valve operates counter-clockwise to open, clockwise to
close.
VERIFY OPERATING POSITION
Verify that the ball open / closed position matches the
gear or actuator open / closed position indicators.
Verify that the scribed lines on the stem 05 align with
the scribed lines on the gland flange 07. These lines
are approximate indications. For best results, make
sure the lines never under travel — a minimum travel
of 97° is required.
Note:
Misalignment can result in valve under- or over-stroke, creating a
potential leak path and affecting warranty.
These procedures are for flanged end connections.
When securing other end types, please contact
MOGAS Service for proper procedures.

Valve item numbers shown in bold correspond with items shown in the
Valve Item Reference Number section (pages 4–5) of this document.
