YUANDA valve has been in line of manufacturing Cast Iron Gate Valve, stainless steel valve for many years. Gate valve is a valve with feature of small flow resistance. Its advantage is as following:

1. The gate valve internal media channel is straight, the medium flows in a straight line, the flow resistant is small.

2. Compared with globe valve, it save effort when open and close.

3. Long time when opening and closing, so water hammer phenomenon is not easy to happen.

But between the sealing surface, it is easy to cause erosion and abrasion, so maintenance is a little difficult. Size is large, when it open, it need some space. And its structure is complex. Pay attention to installation that hand wheel, handle and transmission are not allowed for using lifting, and prohibited collision.
