Installation, Operation and Maintenance Manual
INSTALLATION
Certified lifting devices that are rated for the valve weight should be used when lifting any TK Valves.
For valve sizes 1.5” up to 4”, 6” class 150 thru 900, and 8” class 150 thru 300 the lifting points should be
around the valve neck on either side. For all other valve sizes, lifting lugs will be provided to assist in
lifting the valve.

TK Valves are bidirectional and are tested at the factory to provide a tight shut-off from either direction.
Special instructions will apply if the valve is required to be installed with the stem in the down position.
Actuator and Gearbox stops are preset at the factory and should require no further adjustments. With the
exception of ‘fail-safe closed’ valves, all other valves are shipped in the open position. Valves should not be
closed until the bore of the valve has been cleaned of all debris.
Take caution with the ‘fail-safe closed’ valves. The ball surface is exposed and particularly vulnerable to
weld slag. This surface must be protected when welding nearby.
Sand blasting and painting of valves not in-line should only be done with protective covers on the end
flanges and/or weld bevels (to avoid the ingress of sand into the ball and seat area).
Care should be taken not to blast the RTJ groove or the raised face gasket sealing surface.
Weld-end valves also require care to avoid over heating. Industry work procedure should be followed when
welding valves into surface.
