A check valve refers to a kind of valve with a round valve disc as the opening and closing part and acting by its own weight and medium pressure to block the reverse flow of the medium.

A stop valve is a valve in which the separating element moves along the center line of the valve seat. Since this type of stop valve has a fairly short opening or stem tip stroke and a reliable shut-off function, while the change in the opening of the stop seat corresponds to the stroke of the separating element, it is very suitable for flow-related regulation. So it is very suitable for flow-related regulation. Therefore, this type of stop valve is very suitable for shut-off or adjustment and throttling. Next, let's take a look at the selection principles and characteristics of a stainless stop Check valve.

Gate valves compared to other valves, the pressure, temperature, caliber, and other requirements of the applicable range to a wide range. So from the performance, how to choose it?
