Features:
- The fluid resistance is small, and the sealing surface is less brushed and eroded by the medium.
- Easy to open and close.
- The flow direction of the medium is not limited, and the pressure is not disturbed or reduced.
- Simple shape, short structure length, good manufacturing process, wide range of application.
- Unique self-sealing design, the higher the pressure, the more reliable the sealing.
