Triple Eccentric Flanged Butterfly Valve
Product Features
Excellent sealing performance: Adopting a triple-eccentric structure, the valve disc can closely fit the valve seat when closed, achieving bidirectional sealing. The sealing level can reach zero leakage. Even under working conditions with high pressure differences and high flow rates, it can maintain a stable sealing effect.
Long service life design: The contact surface between the valve disc and the valve seat has undergone special treatment and has excellent wear resistance and corrosion resistance. The triple-eccentric structure makes the friction between the valve disc and the valve seat extremely small during the opening and closing processes, greatly extending the service lives of the valve seat and the valve disc.
Low operating torque: The unique triple-eccentric design significantly reduces the torque required for the valve disc during the opening and closing processes, making the operation easier and more convenient. Meanwhile, it also reduces the energy consumption and wear of the driving device.
Bidirectional sealing function: It is not restricted by the flow direction of the medium and can achieve bidirectional sealing. There is no need to consider the flow direction of the medium during installation, which improves the flexibility and convenience of installation.
Multiple driving methods: It can be equipped with various driving devices such as manual, electric, pneumatic, and hydraulic ones to meet different working conditions and operation requirements. Some rotary electric devices, pneumatic devices, etc. can achieve remote control and automated operation, improving work efficiency.
