Pneumatic hard-sealed flanged butterfly valve

Overview:

The pneumatic hard-sealed butterfly valve adopts a multi-layer structure compatible with both hard and soft seals. It can ensure excellent sealing performance in both low and high-temperature working conditions. Moreover, when the valve is opened and closed, there is basically no friction between the disc and the valve seat, which greatly extends the service life of the butterfly valve. Pneumatic hard-sealed butterfly valves are widely used in pipelines carrying media such as oil products, steam, air and sewage, for on-off control or flow regulation.
