NSEN Weld type Triple offset butterfly valve could provide both laminated sealing and fully metal sealing. Forged body is to be applied for this series, it could avoid internal looseness that cannot be seen during the casting process and the defects of body strength and axial force by plate welding process. NDE inspection will be done if requested by clients, we could provide the service to arrange it.

• Friction free between seat and disc sealing

• Tilted cone sealing face

Valve Marking: MSS-SP-25

Design & Manufacture: API 609, EN 593

End Connection: ASME B16.25

Test and Inspection: API 598, EN 12266, ISO 5208


Triple offset butterfly valve add a third angular eccentric based on double eccentric structure. The third offset is consist of an certain angle between center line of valve body and conical seat sealing face, it ensure the sealing ring of the disc can be separated or touched with seat rapidly so that friction and squeeze between seat and sealing ring will be eliminated.

Friction free design

The use of triple eccentric structure reducing the friction during switching between the sealing surface of the disc and valve body, so that the disc can quickly disengage the valve seat when the triple eccentric butterfly valve is opened or closed.

Low opening torque

This serial uses the Radial Dynamically Balanced Sealing System,by means of optimized design, the forces undertaken on both sides for the butterfly disc inlet and outlet become approximately balanced so as to effectively lower the valve opening torque.

Lubricated bearing

In order to reduce the operation torque and avoid lock of stem under frequently open and close, a customized self-lubricating bushing has been applied.
