进口V型球阀是一种芯阀座采用金属，或金属对聚四氟乙烯密封配合的旋转球阀，它将球阀和蝶阀的最佳控制特性结合成一体,既可用作控制调节阀，又可作关断切断阀。其主要特点是：
（１）不带任何管接头的整体式阀体，因此不受管道或螺栓应力影响，并且由于阀体无任何管接头，故耐压壳体不会受压力“突变”的影响；
（２）具有一个Ｖ型阀体，即使在小流量或高粘度介质的情况下，也可在整个量程范围内，保证控制的精确性；
（３）防漏耐用的阀座在其外径处衬有带不锈钢内芯ＰＴＦＥ杯形或是Ｏ型密封圈，阀座用截面较大的钨钴硬质合金制成，通过一个合金的波纹弹簧进一步增强了阀座的结构；
（４）当阀门关闭时，Ｖ型缺口与阀座之间产生楔形剪切作用，并既具有自洁功能又可防止球芯卡死，特别适用于管线结垢冻结或含有纤维和颗粒固体场合。

适用于高粘度、悬浮液、纸浆等不干净、含纤维介质场合。采用直连方式与执行机构连接，具有结构紧凑、尺寸小、重量轻、阻力小、动作稳定可靠等优点。执行机构根据用户要求配置UNIC、PSQ、HQ、DHL等型号电子式电动执行机构或GTX、AL等气动活塞式执行机构。

Import V-ball valve seat of a core metal, or metal PTFE seal with rotating ball valve, it ball and butterfly valves control features combined into one, and both can be used as a control regulating valve, but alsofor off shut-off valve. Its main features are:
(1) without any pipe joint piece body without pipe or bolt stress, and because the body without any pipe joints, the pressure shell is not affected by the pressure "mutation" of the impact;
(2) has a V-shaped valve body, even in the case of small flow or high viscosity media, but also in the entire range to ensure the accuracy of the control;
(3) leakproof durability of the valve seat at its outer diameter, lined with stainless steel inner core PTFE cup-shaped or O-ring, the valve seat with a larger cross-section of the tungsten-cobalt cemented carbide by an alloy corrugated the spring further enhanced the seat structure;
(4) When the valve is closed, the V-notch between the valve seat wedge shearing, and both have a self-cleaning function and prevents the ball core stuck, especially suitable for pipeline scaling freeze or containing fibers and particles of solid occasions .

Applies to the high viscosity, suspensions, such as pulp is not clean, the fiber-containing media occasions. With Direct Connect connection with the executing agency, with a compact, small size, light weight, small resistance, stable and reliable action, etc.. Implementing agencies according to user requirements the model electronic electric actuators configure the UNIC PSQ, HQ, DHL or GTX, AL pneumatic piston actuator.
