Q: The difference and use of gate valve and stop valve: Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!
