INSTALL MOUNTING FLANGE ADAPTOR
Verify that the handlever
53
recess in the stem
adaptor
13
is oriented 90° to the bore in
closed
position.
Position mounting flange adaptor
51
onto mounting
flange. The open quadrant of the mounting flange
adaptor
51
must allow the handlever
53
to travel
counter-clockwise to an inline position with the bore.
Insert hex head bolts
18
from underside and tighten
temporarily to allow repositioning of the mounting
flange adaptor when setting the stop positions.
INSTALL HANDLEVER
Install handlever
53
into recess of stem adaptor
13
,
aligning the mounting hole as required.
The handlever
53
should be positioned 90° to bore for
closed
, and inline with bore for
open
.
Install hex head bolt
25
through handlever
53
into top
of stem
05
. Tighten as required.
Note:
Some installations may require a washer between hex head screw and
handlever.
Note:
Holes are provided in the handlever and mounting flange to allow locking
the handlever
open
/
closed
position per customer specifications.
VERIFY OPERATION
Note:
The MOGAS valve operates
counter-clockwise to open,
clockwise to
close
.
Using the handlever
53
, the valve should be stroked
to ensure that the ball
01A
is rotating properly, and
the ball position matches the
open
/
closed
position
of the handlever
53
.
To adjust stop positions, loosen hex head screws
18
and carefully reposition the mounting flange adaptor
51
as required.
The
fully
open
position is the most important position
to set. It is preferred that the
open
position be set
before
the valve is installed in the pipeline.
The
fully open
position should properly align the bore,
ensuring that no edges of the ball
01A
are exposed to
the flow.
For visual verification of
open
/
closed
, locate the
scribed lines
on the stem adaptor
13
, stem
05
and gland flange
07
. These lines are approximate
locations and should not be used for setting the
open
stop. For best results, ensure the lines never under
travel — a minimum travel of 96° is required.
When the
open
/
closed
position is properly set, the
scribed lines on the stem adaptor, stem and gland
flange should match.
Fully tighten hex head screws
18
to secure the
mounting flange adaptor
51
in place.
CAUTION!
Misalignment can result in valve under- or over-
stroke, creating a potential leak path.
THIS WILL AFFECT THE VALVE WARRANTY.
!
SET STOP POSITIONS
Stroke the ball to ensure proper
rotation.
Fully OPEN position.
