Leybold Venting Valve for any TURBOVAC i Series Turbo Pump, 24 VDC, NC, G 1/8 in. Connector. PN: 800120V0012

This Leybold venting valve can be installed in any TURBOVAC i series turbo pump in the VENT port. This is a normally closed (NC) valve and operates at 24 VDC. It is plumbed into the G 1/8" (BSPP) VENT port, and powered by the 24 VDC (X201) accessory port. This venting valve vents the pump and the forevacuum line when the pump is switched off and thus keeps oil vapor from diffusing back from the forevacuum line. A choke nozzle in the vent port ensures that the pump is not vented too fast. The maximum permissible pressure in the pump must not exceed 1.4 bar (abs.). Use the TURBO.CONTROL i display unit (part number P109168) to set the correct parameters for this valve. See the Serial Interface download for instructions. This normally closed Leybold venting valve has part number 800120V0012.
