Double Eccentric Butterfly Valve Two eccentric,bidirectional seals
Product Introduction
Double eccentric soft seal butterfly valve is a shut-off bicirectional valve with a double offset of the 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.
Working Principle
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.
Parameters of the Double Eccentric Butterfly Valve
Soft seal butterfly valve-Sealing ring on the disc
1. 100% Sealed, zero leakage:self-adjusting elastomer seat is fixed to the discby adjusting retaining ring
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 pins
5. Body seat with automatic surfacing robot surfacing stainless steel
6. Self-lubricating shaft sleeve, reduce operating torque
7. Easy maintenance and handling
8a. Streamlined disc design, 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
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.
Features
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
Soft seal butterfly valve-Sealing ring on the body
For various media with serious corrosive liguids and gases, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strongalkal, aqua recia, etc., the valve body can be lined with rubber, and the valve plate and valve shaft can be replaced with stainless steelin this wav, it can meet the transportation requirements of serious corrosive media.
Features
1. The inner cavity of the valve body is lined with glue to ensure that the medium is isolated from the metal valve body and improve the reliability of the product
2. Lining material can be selected according to different media
3. Adjusting retaining ring, valve disc, valve shaft and other internal parts can be selected according to different media
4. The selection of non-toxic, antibacterial, aging resistant, corrosion resistant rubber material, long service life5. Bidirectional seal zero leakage
