Plug Valve

A plug valve is a type of valve that controls the flow of fluid by rotating a conical/cylindrical plug with a channel. Its core features are as follows:

Rotate the plug body 90°, so that its channel aligns with (to open) or misaligns with (to close) the pipeline, achieving rapid cutoff of the medium. ‌

The basic type relies on the precise fit between the plug and the valve body; the oil-sealed type enhances high-pressure sealing by injecting grease.

Due to its simple structure and quick operation, it has significant advantages in systems that require rapid shut-off and do not have high requirements for medium cleanliness.

Structural reliability and maintenance convenience

01
Compact and lightweight
With fewer components and a smaller size, it is easy to install and maintain;
02
High temperature/high pressure adaptability
The oil film sealing design can withstand pressures up to 64 MPa, and the surface treatment of hard alloy enhances wear resistance;
03
Multi-channel design
The three-way/four-way structure can replace multiple valves, simplifying pipeline layout (such as in chemical reaction systems).

Excellent medium adaptability

01
Resistant to particulate media
Rotating 90° can achieve fully open/fully closed action, with a response speed far exceeding that of multi-turn rotary valves (such as gate valves), making it suitable for applications requiring emergency shutoff.
02
Bidirectional sealing
No installation direction restrictions, supporting both forward and reverse flow of the medium.

Extremely low fluid drag

Extremely low fluid drag
01
When opened, the inner diameter of the channel matches that of the pipeline, forming a straight-through flow path. The flow resistance is close to that of the pipeline itself, significantly reducing energy consumption.
