Brief introduction of hard seal rising stem gate valve:

Gate valve is one of the widely used industrial valves in fluid transport projects to cut off the mediums. It has compact structure, reasonable design, smooth passage, large flow coefficient,small flow resistance and simple structure. It is easy to maintain. The sealing surface is using the brass or the body material, which has the long service life. The packing material is flexible graphite, which has reliable sealing effect. And its flexible to operate.

Characteristics of hard seal rising stem gate valves:

1.compact structure, reasonable design, smooth passage, large flow coefficient, small flow resistance, simple structure, easy to maintain.

2. flexible graphite as packing material, it is reliable in sealing, light and flexible to operate.
