V型調節球閥是球閥的一種，它的關閉件是半球體上開有V 字型開口，V型開口具有鋒利的刃口，在球體回轉過程中，關閉 件之間有擦拭作用，對介質具有強有力的切斷力，球體的V型開 口與閥座流道形成一個扇形區域，在回轉過程中可改變流道截 面積，形成對介質的精確調節，它是一種角回轉的調節閥，其 密封性能與普通球閥相同，使它同時具備調節和開關兩種功能， 與氣動或電動執行器配套，廣泛使用于工業過程自控系統中。 

Of V-type regulating ball valve is a kind of ball valve， it shutdown a is half sphere has aV opening， v-shaped opening has a sharp edge， in the process of rotating sphere， wiping， between the closed to the media has a strong cutting force， the sphere of the v-shaped opening port to form a fan-shaped area， with the valve seat can change the port area， in the process of rotary forming of medium precision adjustment， it is a kind of Angle of rotation of the regulator， the same as the common ball valve sealing， make it have a combination of regulation and switch two functions， equipped with pneumatic or electric actuators， widely used in industrial process control system.
