Germany KSB KSB DN50 butterfly, with excellent anti-friction, self-lubricating, operating torque lower than normal, a pin butterfly forty percent; for temperature ≤120 ℃ or ≤150 ℃, nominal pressure ≤1.6MPa drainage , sewage, food, heating, gas, shipping, hydropower, metallurgy, energy systems, and textile and other industries, especially for two-way valve seal and easily corroded occasions, regulating traffic and closure of media.
德国凯士比KSB DN50蝶阀，具有优异的减磨、自润滑性，操作力矩比普通有销蝶阀降低百分之四十；适用于温度≤120℃或≤150℃，公称压力≤1.6MPa给排水、污水、食品、供暖、燃气、船舶、水电、冶金、能源系统以及轻纺等行业，特别适用于双向密封和阀体易锈蚀场合，作调节流量和截流介质。
Structural features:
· Integration penetrating shaft: ensure precise valve POSTTTIoning strength, reliability combined valve plate.
· O-ring: helps prevent shaft leakage.
· Precision Taper Pin: vibration proof, shaft to disc plate. Can be replaced in the field.
· Precise and accurate contour disc: to prevent the "bubble tight" shut difficult to ensure maximum effective torque, extending seat life.
· Supported Shaft Seal: elastic material with a phenolic backing ring of close combination, effectively preventing the leakage of distortion caused by the shaft.
· Both for gaseous medium, it is also applicable to a liquid medium.
It can be two-way Close
· Alternative repair pipeline terminal
结构特性：
