V型口球阀为通用型阀门，设计用于准确控制纤维性悬浮颗粒以及清洁、污浊、粘性及腐蚀性液体和气体的节流控制。阀门设计可满足对动态性能的最高工业标准的要求。带法兰或无法兰设计满足美国机械工程师学会（ASME）或美国仪器学会(ISA)面对面尺寸要求。设计特点包括防吹出阀杆保护，高流量，球到轴之间采用花键连接以减少维护并消除回转间隙。阀座选件包括柔性金属、刚性金属及增强聚四氟乙烯阀座。
V-Port Ball Valves are versatile valves designed for accurate throttling control of fibrous suspension applications plus clean, dirty, viscous and corrosive liquids and gases. They are designed to meet the highest industry standards for dynamic performance. Flanged or flangeless designs meet ASME or ISA face-to-face dimensions. Design features include blow-out proof shaft protection, high flow capacity, splined ball-to-shaft connection for ease of maintenance and zero backlash. Seat options include flexible metal, rigid metal and reinforced PTFE seats.
