1.The closer you are, the tighter you get
The sealing performance is more tight and reliable.

2. Brass surfacing technology
Seal material choice brass welding process, long service life.

3. Low fluid resistance
The fluid resistance is small, and the sealing surface is less eroded and eroded by the medium.

4. Large flow area
The flow direction of medium is unrestricted, and the pressure is not reduced.

5. Simple shape
Simple body, short structure length, good manufacturing technology, wide range of use.

6. Bidirectional seal
The mounting direction is not controlled by the flow direction of the fluid medium, nor by the spatial position.

7. Unique structure
Unique structure, flexible operation, labor saving, convenient.
