Flange butterfly valve main features
Flange butterfly valve main features are:
1. Compact and light, easy to disassemble and maintain, and can be installed in any position.
2. Simple structure, compact, small operating torque, 90° rotary opening fast.
3. Flow characteristics tend to be straight line with good regulation performance.
4. The connection between butterfly plate and valve stem adopts no pin structure to overcome the possible internal leakage point.
5, butterfly plate outer circle adopts spherical shape, improve the sealing performance and extend the service life of the valve, with pressure opening and closing more than 50,000 times still maintain zero leakage.
6. The sealing parts can be replaced, and the sealing can reach two-way sealing reliably.
7, butterfly plate can be sprayed with coating layer according to user requirements, such as nylon or teflon.
8. The valve can be designed as flange connection and clamping connection.
9. The driving mode can be manual, electric or pneumatic.
Flange butterfly valve is suitable for temperature ≤120℃ or ≤150℃, nominal pressure ≤ 1.6mpa water supply and drainage, sewage, food, heating, gas, shipping, hydropower, metallurgy, energy system and light textile industries, especially for bidirectional sealing and valve body rust prone occasions, as the flow and closure medium.
