Big Size API6D Trunnion Ball Valve with Gear Operation

The J-VALVES Big Size API6D Trunnion Ball Valve with Gear Operation  employ investment or shell cast bodies & tailpieces, all produced from ASTM grade materials that are properly heat treated and chemically finished. All wall thicknesses comply with ASME B16.34 as do bolting stress levels.

Industrial and Oil/Gas piping applications requiring the higher flow capacity and lower pressure drop of full port internal flow-ways, and those applications where ease of repairability is desired.

Big Size API6D Trunnion Ball Valve with Gear Operation, constructed, and tested according to API and ASME/ANSI Standards. Other international standards including BS and DIN are also available upon request.

5. Big Size API6D Trunnion Ball Valve with Gear Operation Low Operating Torque:

The trunnion pipeline ball valve adopts the trunnion ball structure and floating valve seat, so as to achieve lower torque under operating pressure. It uses self-lubricating PTFE and sliding bearing to reduce the friction coefficient to the lowest in conjunction with the high intensity and high fineness stem.

6.Big Size API6D Trunnion Ball Valve with Gear Operation Emergency Sealing Device:

The ball valves with the diameter more than or equal to 6″(DN150) are all designed with sealant injection device on stem and seat. When the seat ring or stem O ring is damaged due to accident, the corresponding sealant can be injected by the sealant injection device to avoid medium leakage on seat ring and stem. If necessary, the auxiliary sealing system can be used for washing and lubricating the seat to maintain its cleanliness.

Note: All the data should be confirmed with the approved drawings of manufacturer.



     We also manufacture other type valves, as butterfly valve, check valve, globe valve, Y strainer, sanitary butterfly valve, sanitary ball and so on.
