Concealed rod hard seal gate valve

The concealed stem gate valve, also known as the rotary stem gate valve, has its stem and nut located inside the valve body and in direct contact with the fluid

The gate is the opening and closing component of a DN200 concealed hard sealed gate valve, which rotates around the valve stem during opening and closing. The direction of movement of the gate valve is perpendicular to the opposite direction of fluid movement, and the hidden stem gate valve cannot be used to regulate the medium. It can only be in a fully open or fully closed state

Structural characteristics of DN200 concealed hard seal gate valve:

1、 Compact structure, reasonable design scheme, low fluid resistance, and unobstructed passage

2、 The sealing surface is made of stainless steel and hard alloy, which effectively improves its service life

3、 Flexible graphite is used as the filler, with good sealing performance and easy and flexible operation

4、 Widely used and plays an important role in medium pipelines

5、 There are many driving methods for concealed gate valves, such as manual, electric, gear transmission, and pneumatic; Its structural forms are divided into: double gate models, rigid wedge single gate models, and elastic wedge single gate models
