The IVBX, VX series keep particles that are produced inside the chamber from rising. By controlling the integrated bypass valve before opening the main valve, it suppresses abrupt pressure fluctuation that occur when exhausting from air to vacuum, or when going back from vacuum to air. Fixed flow bypass valves and variable flow bypass valves are available. These bypass valves are compatible with all IVB, IVBL, and IVBH series valves except for the 15A size.

Cv: From 0.3 t0.85 available.

• Specifications :
  • They help achieve reduced cost and space saving by integrating the conventional slow bypass line to the main valve.
  • VX type bypass valve can change the conductance to reach optimal exhaust speed. Please refer to the table below for the adjustable range.
  • By selecting high temperature resistant materials, these bypass valves can be used with IVBH series vacuum isolation valves in heated condition.
  • Depending on the model of the vacuum isolation valve, multiple bypass valves can be attached. Please ask the sales representatives for details.
