气动V型调节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气动球阀，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。

Air is a kind of v-type regulating ball valve core seat using metal, or metal for ptfe seal with the rotation of the ball valve, it will be a ball valve and butterfly valve control features combined into an organic whole, not only can be used as a control valve, cut-off valve and can make off. Its main features are:
(1) with no coupling integral body, so is not affected by pipeline or bolt stress, and because the body without any pipe joint, so the pressure hull would not be affected by pressure "mutation";
(2) with a v-shaped body, even in the case of small flow rate or high viscosity media, can also be within the scope of the whole range, ensure the control accuracy;
(3) the leakproof durable seat at the outer diameter of PTFE lined with stainless steel inner core cup or type O sealing ring, the seat made from cross section larger cobalt tungsten carbide, by a corrugated metal spring to further enhance the structure of the seat;
(4) when the valve is closed, v-shaped gap between wedge and seat shearing action, and both have the function of self-cleaning and can prevent the ball core is stuck, especially suitable for the pipeline scaling or containing fibers and particles frozen solid.
Suitable for high viscosity, slurry, pulp is not clean, fiber media such occasion. USES the direct way to connect with the executing agency, has a compact structure, small size, light weight, small resistance, stable and reliable action, etc. Actuators according to user requirements configuration UNIC, PSQ, HQ, DHL and other types of electronic electric actuators or GTX, AL pneumatic piston type actuators, etc.
