NSEN Metal to metal seal Bi-directional Triple offset butterfly valve adopts the structure of “Metal To Metal Seat ring”, i.e. valve’s sealing ring of disc/seat are all metal with hard faced treatment. The solid metal sealing structure could eliminate the problem of of leakage and unstable sealing performance caused by U-type seat or L-type seat. Besides, our specially sealing design could allow the valve operate in differential pressure without reducing of pipe pressure.

Bi-directional sealing design

This series could reach Zero-leakage requirement for both way in related standard. Bi-directional sealing make the installation with flow in either direction, vertically, or horizontally and without any leakage. The highest pressure ranting could reach is 600LB.

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.

Double safety structure
In order to prevent phenomena of disc deformation, stem misalignment, sealing face biting each other caused by fluid pressure and temperature, NSEN butterfly valve uses two separate thrust rings on the upper and down side of disc which ensures valve’s working under any conditions.
