Relying on advanced technology, excellent production capabilities, and perfect service, SHSUOTE Valve takes the lead in the industry now and spreads our SHSUOTE Valve all over the world. Together with our products, our services are also supplied to be the highest-level. double eccentric butterfly valve design We have been investing a lot in the product R&D, which turns out to be effective that we have developed double eccentric butterfly valve design. Relying on our innovative and hard-working staff, we guarantee that we offer customers the best products, the most favorable prices, and the most comprehensive services as well. Welcome to contact us if you have any questions.double eccentric butterfly valve design The surface of the valve body and bonnet removes impurities such as oil rust and dirt, and is specially treated with a baking varnish process, which is durable and will not be oxidized and rusted even if it is used for a long time.
Double eccentric soft seal butterfly valve is a shut-off bicirectional valve with a double offset ofthe disc.
lt has good fluiccontrol characteristics and closing sealing performance, and is widely used in food, medicine, chemical, petroleum.electric power, textile, paper and other industries .
The eccentric principle is that the stem shaft is both deviated from the valve body center (a), also deviated from the seat (b)The double eccentricity effect allows the butterfly plate to quickly detach from the valve seat when the valve is openedGreatly eliminates unnecessary excessive squeezing and scraping between the butterfly plate and the valve seat, reduce:the valve opening torque, reduces valve seat wear, and improves the service life of the valve seat .
Soft seal butterfly valve-Sealing ring on the body
On the basis of the disc seal butterfly valve, derived body seal structure butterfly valve - the sealing ring is fixed on the valve body. Thestructure also has good fluid control characteristics and closing sealing performance .
1. The automatic adjusting elastomer seat is fixed to the body
2.100% bidirectional seal zero leakage
3. Adjusting retaining ring is fixed to the valve body flange with A2-70 screws, which do not contact the medium
4. Besides the above features, t also has the features of good sealing and low operating torgue of butterfly valve with disc seal structure
Double Offset Butterfly Valve Features
1 . 100 % Sealed , zero leakage : se lf-adjusting elastomer seat is fixed to the discby adjusting retainingring
2. Bi-directional flow sealing with 1.1 x PN
3. Disc seat with high qualiy rubber, regains original shape
4. Adjusting retaining ring fastened with A2-70 screws and extra dowel pins5. Body seat with automatic surfacing robot surfacing stainless steel
6. Self-lubricating shaft sleeve, reduce operating torque
7. Easy maintenance and handling
8a . Streamlined discdesign, reduces the flow resistance coefficient, making thefluid channel more stable , reducing pressure loss and reducing sensitivity folvavitation
8b. Truss type disc design, disc has higher strength, suitable for high pressuregrades and large diameters
