The features of A series butterfly valves' structure are opposite nip and eccentric disc; B series butterfly valves' structure features are with screw hole single flange. The two series disc valves are widely used in food, beverage, pharmaceutical and industrial environmental clean water pipelines, high-rise buildings, blow pipes, etc; as both are eccentric disc and hearts dish plate structure,
so the property of seal are perfect, it also can be used in vacuum-tube line.
Seal Performance :
Lip Shape seal - The valve made of 316 alloy steel, TFE valve seat and the ball shape fan-like disc. Which has the function of stronger compensative flexibility, reliable sealing, anti high temperatures and good anticorrosion
