The Most Obvious Advantages And Disadvantages Of The Globe Valve

The most obvious advantages of globe valve such as DIN angle type Globe Valve are:

(l) during opening and closing, the disc is wear-resistant because the friction between the disc and the sealing surface of the body is less than that of the gate valve.

(2) open height is generally only l/4 of seat channel diameter, so it is much smaller than gate valve.

(3) usually there is only one sealing cover on the valve body and disc, so the manufacturing process is better and convenient for maintenance. But, the drawback of stop valve also cannot ignore.

The main disadvantage is that the flow resistance coefficient is relatively large, so pressure loss is caused, especially in the hydraulic device, such pressure loss is particularly obvious.
