What is the ultra-high pressure shut-off valve? What are the advantages of the shut-off valve?

The ultra high pressure shut-off valve is a type of high pressure shut-off valve. Mainly used in industries with high pressure requirements. The conventional connection method has two types of welding and threading. Butt welding means that the connection method is butt welding. Mainly used in chemical and pharmaceutical fields. Because it is welded. It is not convenient to replace. The main applicable repair is not very frequent and the wear and tear is relatively low.

A shut-off valve is a valve that moves a closure (valve) along the centerline of the seat. Depending on the form of movement of the flap, the change in the seat opening is proportional to the flap travel. Due to the relatively short opening or closing stroke of the valve stem of this type of valve, and the very reliable cutting function, and because the change of the valve seat opening is proportional to the stroke of the valve flap, it is very suitable for the adjustment of the flow rate. Therefore, this type of valve is well suited for use as a cut or adjustment and throttling.

The most obvious advantages of the globe valve are:

(l) During the opening and closing process, the friction between the valve disc and the sealing surface of the valve body is smaller than that of the gate valve, so it is wear-resistant.

(2) The opening height is generally only 1/4 of the diameter of the seat channel and is therefore much smaller than the gate valve.

(3) Usually there is only one sealing surface on the valve body and the valve flap, so the manufacturing process is better and easy to repair. However, the shortcomings of the shut-off valve cannot be ignored. The disadvantage is that the flow resistance coefficient is relatively large, thus causing pressure loss, especially in hydraulic devices, such pressure loss is particularly obvious.
