Product overview of manual V-type ball valve

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。 Manual V-type ball valve is a rotary ball valve whose core seat adopts metal or metal to polytetrafluoroethylene sealing. It combines the best control characteristics of ball valve and butterfly valve into one. For shut-off shut-off valve. Its main features are:
(1) Integral valve body without any pipe joints, so it is not affected by pipeline or bolt stress, and because the valve body does not have any pipe joints, the pressure-resistant casing will not be affected by the "abrupt change" in pressure;
(2) With a V-shaped valve body, even in the case of small flow or high-viscosity media, the entire range can be guaranteed to ensure the accuracy of the control;
(3) The leak-proof and durable valve seat is lined with a stainless steel inner core PTFE cup or O-ring seal at its outer diameter. The valve seat is made of tungsten-cobalt hard alloy with a large cross-section. The spring further strengthens the structure of the valve seat;
不锈钢手动阀门 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,特别适用于高粘度、悬浮液、纸浆等不干净、含纤维介质场合。 (4) When the stainless steel manual valve is closed, a wedge-shaped shearing effect occurs between the V-notch and the valve seat, and it has both self-cleaning function and prevents the core from jamming. It is especially suitable for high viscosity, suspension, pulp Clean, fibrous media.
