CAUTION!
Ensure key
19
length provides and maintains full
engagement.
Supplier of adaption package should provide
key
19
specifications.
THIS WILL AFFECT THE VALVE WARRANTY.
!
MOUNT ACTUATOR
Align key
19
of stem adaptor
13
with keyway of
actuator.
Carefully place the actuator on the valve mounting
flange
14
(or adaptor
51
).
CAUTION!
If the actuator is supplied by MOGAS, refer to the
torque values in the
test certificate
provided for
each individual valve serial number.
Otherwise, refer to the manufacturer’s
specifications.
THIS WILL AFFECT THE VALVE WARRANTY.
!
CAUTION!
Do not force actuator onto stem adaptor. Proper
alignment is critical to ensure the actuator slides
gently into position.
If stem is forced into valve, severe damage could
occur.
THIS WILL AFFECT THE VALVE WARRANTY.
INSTALL BOLTS
Install the hex head screws
18
, and torque as required.
INSTALL KEY
Insert key
19
into stem adaptor keyway.
Note:
Some installations may require inserting the key through an access port
in the actuator, after actuator is in position.
!
VERIFY OPERATION
Note:
The MOGAS valve operates
counter-clockwise to open, clockwise to
close
.
The actuator should be stroked to ensure that the ball
01A
is rotating properly, and the ball position matches
the
open
/
closed
indicators on the actuator.
If the ball requires alignment, the actuator stops
should be reset at this time, per the manufacturer’s
specifications.
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
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 actuator is properly set, the scribed lines on
the stem and gland flange should match.
CAUTION!
Misalignment can result in valve under- or over-
stroke, creating a potential leak path.
THIS WILL AFFECT THE VALVE WARRANTY.
!
SET STOP POSITIONS
Note:
The actuator stops may be reset per the manufacturer’s specifications to
achieve
fully open
and / or
fully closed
position.
Stroke the ball to ensure proper
rotation.
Fully OPEN position.
Set stop positions.
