Materials used in ball valve construction are equivalent at all JKTL manufacturing plants. However,
the availability of local supplies, the need to conform to national standards and to offer various trims may
necessitate some variation. In corrosive applications, valve trims may be offered using various types of
alloy and stainless steel. For more information on material specifications and properties, contact us directly.
The torque stated are for guidance only, they have been obtained by measuring on new ball valve. The
torque is to be understood as the pull-off torque applicable for a closed, but recently activated ball valve.
The valves stated may rise to a factor of 1.5 after a long period of not being in service.
