There are many single-stage and double-stage series bevel gears on the market. Among them, the more common single-stage and double-stage products are MY-VD series and MY-VS series. These two series of products are suitable for use on gate valves and globe valves. Electric device.So how big is the difference between them?Let's take a look at their respective parameters together.

   The MY-V8 speed ratio in the single-stage MY-VD series is 7:1, the thrust is 1587000, and its torque is 28000N·m.Its stem diameter is 150mm and its weight is about 565KG. It is a product with relatively high parameters in this series.

   双级产品MY-V-S系列中的MY-V8-1S的速度比率为115.5：1，推力为1430000，而转矩为26100N·m.阀杆直径为150Mm,重量相对于前面这款产品要更重一些，有645KG，同样也是这个系列中参数较高的产品之一。

   From these two products, we can see that the difference in parameters between single-stage and double-stage bevel gears under the same specifications is not very large. In terms of speed ratio, the MY-VD series may be better, mainly in applications. Only when the working conditions are different will there be a single- and double-level division.
