The VacStable Vacuum Bleed Valve is a small, durable vacuum control valve that has been used in pharmaceutical and R&D applications for more than 15 years. It has a multitude of applications and can be paired with the StrataVac or StataVac Touch product line to both measure and maintain vacuum pressures.

  • All Metal | Rugged design for industrial and R&D applications
  • Bleed Vacuum Valve | Bleed air or other inert gases (like nitrogen or argon) into your system to control and maintain the vacuum level
  • Precise Vacuum Control | For industrial and research applications supports process automation
  • Accurate Stable Control | Time-tested with over 15 years of successful in-field use and an accuracy of +/- 1% of reading
  • Benefits of Bleed Vacuum Control | The bleeding of inert gases into a process helps increase molecular flow which increases throughput and helps improve quality of distillate by avoiding additional time and oxidation in the boiling flask
  • It is compliant with RoHS and delivers bleed vacuum control between 10 mT (millitorr) and 10 Torr
  • Bleed Gas Interface | hose barb for 1/16” I.D. hose
  • Flow rate: off, and settable to 35-3620 sccm
  • Power: 5 Volt, 850 mW
  • Use Case Example—A manufacturers wants to control their freeze drying process better, so they implement this vacuum measurement and control solution to maintain 2 Torr in batches to improve consistency, and can view the ongoing process from any browser by accessing  when paired with a StrataVac Controller with Wi-Fi

Bleed vacuum control |  .010 mBar up to 10 mBar
