This Edwards TAV5 venting valve can be installed in any nEXT85D, 240D, 300D, 400D, 730D, 930D, or 1230H series turbo pump. This is a normally open (N/O) valve and operates at 24 VDC. This TAV5 solenoid valve comes with a 3 meter long power cable with unterminated (bare wire) end, and has a BSPP (G) 1/8" fitting for connection into the pump's vent port. This valve can be powered by the pump's accessory port (nEXT85D, nEXT730D, nEXT930D, or nEXT1230H) or the connector socket (nEXT240D, nEXT300D, or nEXT400D), a TIC Controller, or a separate 24 VDC power supply. For use with an 85D, 730D, 930D or 1230H nEXT turbo pump, the accessory extension cable is required (part number P1012520), which has an accessory connector on one end and is unterminated on the other. For 240D, 300D, and 400D pump's, the valve's unterminated power wire is connected to the pump's (24 VDC) Phoenix connector socket (the mating phoenix plug is supplied with the pump). This normally open valve can be used as a power failure venting valve. When a power failure occurs, this valve closes and vents the pump and the forevacuum line and thus keeps oil vapor from diffusing back from the forevacuum line.

TAV5 vent valves have an 0.5mm diameter orifice and are suitable for venting small vacuum systems of <5 liters (for larger system volumes, use the TAV6 venting valve with an orifice of 1.0mm, part number P106355). The TAV5 vent valve can replace the manual vent valve that is furnished with the turbo pump, or be fitted into any other suitable port on the vacuum system upstream of the turbomolecular pump. This valve is supplied with a 3 meter long unterminated cable, a sintered bronze inlet-filter, a riffled hose connector for attaching to a dry nitrogen supply, and a DN10NW adapter for optional direct connection to the vacuum system. This TAV5 normally open (NO) solenoid venting valve has Edwards part number B58066010.
