Pfeiffer Shielded Sealing Gas Purge Valve for HiPace 80 Turbo Pumps with TC 110 Drive Unit Normally Closed (NC) G 1/8" Male Fitting M8 Connection, PN: PM Z01 310 A

This shielded Pfeiffer sealing gas valve (purge valve) for HiPace 80 turbo pumps with a TC 110 drive unit screws into the G 1/8" (BSPP) sealing gas port of the pump (sealing ring and filter included). It prevents the ingress of damaging substances, such as corrosive materials into the motor and bearing area of the pump. The use of this sealing gas valve also ensures proper rotor cooling and protects the pump from being damaged by high gas throughput (> 50 % of the pump's maximum). This valve allows a suitable, constant flow rate of inert gas (7.5 - 9.5 sccm @ maximum 1.5 bar absolute) into the pump. This 24 VDC normally closed (NC) electric solenoid sealing gas valve has Pfeiffer part number PM Z01 310 A.

This valve has an M8 electical connector that plugs into one of the accessory ports in the TC 110-to-controller cable (part number P103335 or P1011168, sold separately). The TC 110 drive unit controls and supplies power to the valve. Note that the activation (control) of this valve for the sealing gas connection is not pre-installed in the electronic drive unit and must be configured by the using a Pfeiffer controller (OmniControl 200 or DCU 110) or externally via RS485.
