Feature:
1. Little fluid resistance, the resiatance valve is equal to tube of the same length.
2. Simple structure, small size and light.
3. Reliable sealing, PTFE or similar sealing face material, also widely used in the vacuum system..
4. easy operation, open and close rapidly, 90 degree form full open to full close.
5. Easy maintenance, convenient to assemble and disassemble.
6. The sealing face is isolating form medium when full open or close to against the corrosion of the medium.
