The whole welding ball valve adopts welded body structure, The valve is light and it is favorable for heat preservation. There are a variety of connection ways,for example: welding, thread and flange. The valve has a long life which can be used for 20 years due to the special structure.
JKTL fully welded ball valve conform to one or more of the following specifications for pressure,
temperating ratings and dimensions: ASME/ANSI, ISO 14313/API6D, ISO 10423/API6A,
ISO 14723/API 6DSS, DIN, AFNOR, British standards, ISO 9000 and API Q1.

Pressure range ASME/ANSI Class 150 to 2500
Teaperature range -20°F to 250°F (-29℃ TO 121℃)
Body ASTM A350 Gr.LF-2(M)
End connection ASTM A350 Gr.LF-2(M)
Ball ASTM A694 Gr.F50(M) Chrpme plated or ENP
Seat ring AISI 1040
Seat load spring AISI 1040
Stem seals PTFE
Seat ring insert Nylon

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.

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
Upsteam Sealing
At low pressure, seat-to-ball contact is maintained by Belleville Springs. At higher pressures, seat contact is reinforced by line pressure.

Product Description

Packaging & Shipping

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.
