D671X Pneumatic Wafer Butterfly Valve
The D671X pneumatic wafer butterfly valve designed by Dazhong Valve Group, the pneumatic butterfly valve can not only be used to cut off the medium, but also can be used to adjust the flow of the medium. The drive device can be manual, electric, pneumatic, etc. according to user requirements. The connection between the butterfly plate and the valve stem adopts a pin-free structure, and the outer circle of the butterfly plate adopts a spherical shape. The butterfly plate can be sprayed with coatings such as nylon or PTFE according to user requirements. The valve can be designed with flange connection and wafer connection.
D671X pneumatic butterfly valve is suitable for temperature ≤120℃ or ≤150℃, nominal pressure ≤1.6MPa water supply and drainage, sewage, food, heating, gas, ship, hydropower, metallurgy, energy system and light textile industries, especially It is suitable for two-way sealing and the valve body is easy to corrode, and it is used for regulating flow and intercepting medium.
Small and light, easy to disassemble and maintain, and can be installed in any position. The structure is simple and compact, the operating torque is small, and the 90° rotation can be opened quickly. The flow characteristics tend to be straight, and the adjustment performance is good.
The connection between the butterfly plate and the valve stem adopts a pin-free structure, which overcomes the possible internal leakage point. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and prolongs the service life of the valve. It can be opened and closed under pressure. More than 50,000 times and still maintain zero leakage.
The seals can be replaced, and the sealing is reliable to achieve bidirectional sealing. The disc can be sprayed with coatings such as nylon or PTFE according to user requirements.
The valve can be designed as flange connection and wafer connection. The drive mode can be selected as manual, electric or pneumatic.
