KTM 2-WAY, 3-WAY AND V-PORT BALL VALVES
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
PRESSURE TEST
• In case of pressure test of the pipe system,
the valve should be in a half-open position
and check the leakage from joint connection
or gland. If the test is performed with the
valve in close position, overload pressure on
the seat could cause seat leakage.
• The ball valve should be operated to either
full open or closed position. Prolonged use
in a half-open position could cause seat
deformation or seat leakage.
OPERATION
Refer to Figure 2
• The closed position of KTM ball valves is
indicated by either the handlever or the
direction of the parallel flats on the top of
the stem (see picture).
• All standard manually operated valves are
'clockwise to close'.
• The valve requires no 'additional tightening'
to shut off, excessive handle operation could
break the lever, injure the operator, or deform
the stopper or stem which may lead to seat
leakage.

MAINTENANCE
Refer to Figure 3
No routine maintenance is required other
than periodic inspection to ensure satisfactory
operation and sealing. Any sign of leakage
from the gland packing should be addressed
immediately by depressurizing the valve and
tightening the gland screws gradually and
evenly. If no further adjustment is possible,
or if seat or joint leakage is suspected, the
valve will require a complete overhaul. This
should be carried out after depressurization
and in accordance with specific maintenance
Instructions. Only original spares should be
used.
