Bare Shaft Vulcanized Seat Flanged Butterfly Valve

The biggest feature of this valve is the dual half-shaft design, which can make the valve more stable during the opening and closing process, reduce the resistance of the fluid, and is not suitable for pins, which can reduce the corrosion of the valve plate and valve stem by the fluid.
