Vacuum Pump Isolation Valve (VPI), NW40,220 V, 50/60 HZ, Agilent Technologies (CAT#: STEM-LE-0303-Y)

Vacuum Pump Isolation Valve (VPI) is manufactured by Agilent Technologies. VPI and mechanical pumps are electrically connected in parallel. It can be quickly shut down even when the power is turned off, thereby preventing oil from flowing back or particles from entering your vacuum system. The valve also evacuates the pump from the inlet side, so that all debris can be pushed to the outlet, thus preventing debris from being flushed into the system when the pump restarts.

Dry scroll pump.

• Adopt central locking mechanism to achieve reliable and repeatable sealing
• In the event of power failure, the valve closes within 30 milliseconds to prevent the migration of oil or contaminants and provide timely protection for your vacuum system
• Vent the pump on the pump inlet side, keeping the flow direction unchanged oil/debris will not flush into the system
• Keep closed before the pump inlet pressure returns to the system pressure to provide continuous protection and facilitate restart
• Operates at atmospheric pressure and is performed when power is turned off without compressed air
• Provide maximum conductivity without reducing pumping speed
