Replacement Solenoid for Agilent Vacuum Pump Isolation Valve.
The VPI is electrically connected in parallel with your mechanical pump, and closes rapidly when power is interrupted to prevent oil backstreaming or particle migration into your vacuum system.
The valves also vent the pump from the inlet side to push any debris towards the outlet, thereby preventing it from being swept into the system when pumping is restarted.
The body design and right-angle configuration provide maximum conductance.
Edwards A50637392 cable directly connectsVIV25EKA and VIV40EKA to Edwards nXRi series dry vacuum pump.
