Vari-Q Throttling Valve
Vari-Q Throttling Valve Provide improved conductance control than butterfly valve. The vanes are counter-rotated providing optimal pressure control over wide range of operaton. In the open position, the low-profile vanes offer little restriction in the pumping path.
Vari-Q valve is the industry's standard of choice for valve size 4" and up
- Linear conductance control
- High repeatable
- Low profile
- Upstream or Downstream pressure control
- Corrosion Resistant
- Sizes from 4" to 35"
- Available in SST or Aluminum
- Available in RS232 or 1-10 V DC
- Build-in diagnostics
- Manual override for set up and maintenance
