Hard Sealed Flange Butterfly Valve

Short Description:

The butterfly valve adopts the principle of three dimensional eccentric design, which adds a unique eccentricity on the original double eccentric foundation. It not only takes advantage of the original cam effect, but also completely eliminates the friction between the valve plate and the sealing ring in the 90 degree rotation.

Product Tags

By optimizing the contact angle between the butterfly plate sealing surface and the seat sealing ring, the contact angle of the valve is larger than the locking cone angle range. In terms of geometry, the possibility of butterfly plate jamming is excluded, thus ensuring the required torque of the valve switch. The butterfly plate sealing surface can be inlaid with stainless steel sealing ring or directly surfacing stainless steel or carbide on the butterfly plate to ensure the durability of the valve in various uses, including high temperature and unclean working conditions.
