Agilent Vacuum Pump Isolation Valves (VPI) are electrically connected in parallel with the mechanical pump, and close rapidly when power is interrupted to prevent oil backstreaming or particle migration into your vacuum system. These protection valves also vent the pump from the inlet side to push any debris towards the outlet, preventing it from being swept into the system when pumping is restarted. The body design and right-angle configuration provide maximum conductance.

Features:

  • Reliable, repeatable seals with lock-over-center mechanism
  • Fast-acting, immediate protection of your vacuum system from oil or contaminant migration in case of power failure, valve closes in less than 30 milliseconds
  • Provides venting of the pump at the pump inlet, flow direction is maintained; oil/debris are not swept into the system
  • Remains closed until pump inlet pressure returns to system pressure for continued protection and easy restart
  • Operates with atmospheric pressure and is activated upon loss of electrical power, no compressed air required for operation
  • Provides maximum conductance, no reduction of pumping speed
