Overview

D342X double eccentric soft seal flange butterfly valve, the double eccentric structure is formed during the design process, where the disc deviates from the sealing centerline surface to form the first eccentricity; The valve stem deviates from the centerline of the pipeline, forming a second eccentricity; Two eccentric structures seal the valve for opening and closing. The smaller the angle of rotation of the disc during the manufacturing process, the easier it is to disassemble the seat, reduce friction, and thus extend the service life of the valve.

D342XDouble eccentric soft seal flange butterfly valve

One,D342X-10C_ Double eccentric soft seal flange butterfly valve - Overview

D342X-10C_ Double eccentric soft seal flange butterfly valve is suitable for regulating the flow of urban water supply and drainage and power oil systems as an interception section.

Secondly,D342X-10C_ Double eccentric soft seal flange butterfly valve - Structural principle

The double eccentric structure is the first eccentricity formed by the deviation of the disc from the sealing centerline surface during the design processThe valve stem deviates from the centerline of the pipeline, forming a second eccentricity; Two eccentric structures seal the valve for opening and closing. The smaller the angle of rotation of the disc during the manufacturing process, the easier it is to disassemble the seat, reduce friction, and thus extend the service life of the valve.

Three,D342X-10C_ Double eccentric soft seal flange butterfly valve - Product features

1. The butterfly plate adopts a streamlined design, with low valve resistance and low pressure loss.

2. Adopting a double eccentric structure reduces friction on the sealing surface and extends the service life of the valve. Emergency shut-off valve

3. The butterfly plate sealing ring adopts a T-shaped structure, and the valve seat is made of high-performance wear-resistant copper material. The sealing pair is linearly sealed, and the opening and closing torque is small. ### 4. The sealing ring is easy to replace and maintain.

5. The sleeve is made of wear-resistant copper material, and the valve shaft seal is sealed with O-ring, which is wear-resistant.

6. The product can be installed vertically or installed properly with good applicability.

sealing ring NBR、EPDM

The D342X flange double eccentric butterfly valve has a compact structure, easy 90 ° rotary switch, reliable sealing, and long service life. It is widely used in water plants, power plants, steel mills, papermaking, chemical, catering and other systems for water supply and discharge, as well as for regulating and shut-off purposes. Performance characteristics: 1. Simple and compact structure, light weight, 90 ° rotation, flexible and rapid opening and closing. 2. Adopting an eccentric structure to reduce the friction of the sealing ring and extend the service life of the valve. The sealing structure design is reasonable, achieving sealing and zero leakage, and can adapt to harsh working conditions. 4. Replace the valve plate sealing ring, O-ring, valve plate, shaft and other materials, which can be used for various media and different temperatures. The valve body has foot support, which can achieve vertical or horizontal installation of the valve. Easy to assemble and disassemble, convenient for maintenance.
