3 Offset Butterfly Valve

◆ Triple eccentric Multi-level butterfly valve with floating sealing: 1. To create a bi-direction 1:1 seal, the floating metal seat design reduces torque and extends serve-life by allowing the seat and sealing ring to automatically fit under the promotion of the medium. 2. The metal and non-metal composite seal is more firmly sealed, enabling the realization of high pressure and temperature operating conditions. 3. eccentric design with triple offset,The torque of the valve stem is directly transmitted to the sealing surface through the butterfly disc when the valve is turned on and off, preventing the butterfly disc from scratching the valve seat and eliminating the lack of control brought on by unstable variables like friction in the low opening range of the valve.
