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.

Fire-Tested for Safety
JKTL fully welded ball valves can be supplied to API6FA, API607 and ISO 10497 standards. If industry standards change or customer requirements vary from the above, please contact your sales representative.
Trunnion Mounted Ball Allows Low-Torque Operation
Regardless of size or pressure rating, every JKTL fully welded ball valve is trunnion mounted. High-strength forged stems are located in PTFE impregnated stainless steel bearings for smooth, accurate operations. Trunnion mounted stems absorb the thrust from line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure, operating torque stays low.
Test Valve Integrity
When the valve body is vented, the seat seal’s integrity is verified. This test can be performed with the valve open or closed. Valve performance can also be validated by verifying valve seat seal integrity.
Features and Benefits
At low pressure, seat-to-ball contact is maintained by Belleville Springs. At higher pressures, seat contact is reinforced by line pressure.
We use high quality plywood wooden case packing which avoid fumigation.It have good cushioning performance,high strength,and corrosion resistance.The use of foam film cover the valve better to protect the valve body and fixing wooden cases is the final step.
