Butterfly valve standard overview and structural applications
New product structure of high performance butterfly valve seat design, according to the direction of the pressure source, automatically adjust seat, achieve the effect of double valve with pressure, and increase the service life of the valve seat, butterfly valves service life is long, with special valve shaft dustproof design, prevent the fluid into the cause of the valve shaft jammed valve shaft are high performance butterfly valve in different working condition, can choose different material and performance, Valve seat is pumped with PTFE, RTFE, PEEK, METAL and other materials, suitable for petrochemical, oil refining, air separation, CDA and other conditions.
Butterfly valve structure application:
Butterfly valve is characterized by fast opening and closing speed, simple structure, low cost, but the tightness and bearing capacity is not good. At present, butterfly valve has been widely used in many fields, such as petroleum, chemical industry, metallurgy, water and electricity, as a part used to realize the on-off and flow control of pipeline system. The sealing form of sealing structure, sealing materials for rubber, ptfe and so on. Due to the limitation of structure characteristics, it is not suitable for high temperature, high pressure, corrosion resistance, wear resistance and other industries.
