  • Product Profile

    Triple offset butterfly valve is a unique angular eccentric on the basis of double eccentricity, completely eliminate all the friction between the valve seat and the sealing ring in the 90 stroke, especially in some high temperature, high pressure or low temperature conditions, compared with the gate valve, ball valve has an obvious cost-effective advantage. It is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage and municipal construction and other industrial pipelines to regulate flow and cut off fluid.


  • Design Feature

    1.The elastic metal steel sheet sandwich seal makes the valve have zero leakage performance. 


    2.The right-angle rotation frictionfree design is achieved through a unique three eccentric principle, 0~90 degrees between the valve seat and butterfly seal ring friction, remove the possibility of wear and leakage, prolong the service life of the valve. 


    3.Torque seal can ensure the two-way zero leakage requirements in the long-term operation of the valve, and the valve switch life can reach 500,000 times. 


    4.All-metal structure + zero leakage performance, so that the valve has the essence of fire prevention and safety characteristics. 


    5.The butterfly valve adopts precision casting process, including the valve body and valve plate of the valve. This valve process has many advantages compared to the steel plate rolling process, the most important is that the overall strength of the valve is high, and relatively speaking, the cost of the valve is also higher than the rolling process. 


    6.The anti-proof valve stem is safe and reliable and meets the requirements of API 609. 


    7.A variety of packing structure forms to meet the requirements of different working conditions.
