详情介绍:
Edwards TAV5 Air Admittance Vent Valve for EXT or nEXT Turbo Pumps, 24V DC 1/8 BSP Thread, 1.8 Watts Max.
PN: B58066010

The Edwards TAV5 vent-valve is 24 V DC solenoid operated valve which can be use to vent your Edwards Turbo EXT or nEXT vacuum system with atmospheric air or dry nitrogen when you switch off the Turbo pump. The valves are supplied with a sintered bronze inlet-filter, a riffled hose connector, 3m of electrical cable and a DN10NW adapter. The valve can be driven by the Podule attached to the Edwards EXT 75DX Turbo Pump, a TIC controller, EXC controller, the drive electronics connector on the side of nEXT pumps, or any suitable 24VDC power supply. You can either use your TAV5 vent-valve to replace the manual vent-valve supplied with the EXT 75 DX pump or nEXT series pumps, or adapt it to fit any other suitable port on the vacuum system upstream of the turbomolecular pump. This is the TAV5 vent valve only, EXT and nEXT turbo pumps sold separately. For application use and install instructions see Accessory Manual PDF below.


    The TAV5 Vent-Valve Can be Used:
  • In place of the manual vent valve on the EXT 75DX pump or nEXT series turbo pumps
  • Solenoid valve connected to a convenient flange on your vacuum system
