Product Description

Features:

1. The butterfly valve adopts a unique design structure with bidirectional metal sealing, and the eccentric S-shaped valve seat sealing surface can limited improve the valve's lifespan.
2. Low operating torque, rotating 90 ° to open and close, and easy to switch.
3. Low flow resistance, good hydraulic characteristics, flow characteristics approximately in a straight line, bi-directional sealing, and no special requirements for installation direction.
4. The seal is reliable, and the Maximum life span can be 25000 times of switching.
