Cast Steel Flanged Triple Eccentric Butterfly Valve
Product Features:
Excellent Sealing Performance: Adopting a multi-layer sealing ring design, combined with stainless steel and non-metallic materials, it achieves bidirectional sealing. The leakage level can reach Class V, and in some cases, even zero leakage can be achieved.
Long Service Life: The triple eccentric structure allows the butterfly disc and the sealing ring to separate rapidly when opened, reducing the wear of the sealing ring. Meanwhile, when the butterfly disc is closed, it expands outward to achieve the best peripheral sealing effect, further prolonging the service life of the sealing ring.
Low Operating Torque: Thanks to its unique structural design, the operating torque is greatly reduced, making the operation of the valve easier and more convenient, and also reducing the requirements for the actuator.
Good Self-cleaning Ability: During the opening process, the butterfly disc can automatically remove impurities on the sealing surface, keep the sealing surface clean, and thus further improve the sealing performance and service life of the valve.
Wide Applicability: It can be applicable to a variety of media, including water, steam, oil products, natural gas, acidic and alkaline liquids, etc. It has a wide working temperature range, with the maximum temperature reaching over 200 °C. Some special materials can even withstand higher temperatures.
Multiple Connection Methods: It provides various connection methods such as flange connection and wafer connection, which are convenient and flexible for installation and can meet the connection requirements of different pipeline systems.
Multiple Driving Methods: It can be equipped with various actuators such as manual, electric, pneumatic, and hydraulic ones, and can also realize remote control to meet the operation requirements under different working conditions.
