Pressure
Technical Features
Double eccentric high-performance butterfly valve, with elastic seat, can easily achieve zero leakage and more reliable sealing. The elastic valve seat design can achieve lower torque and reduce the procurement cost of the driving device. Soft sealing materials such as PTFE have good adaptability to acidic and other media, making them highly adaptable to various working conditions.
