Pfeiffer Venting Valve for the 300H Turbo Pumps with TC 110 Drive Unit, Normally Closed (NC), G 1/8" Male Fitting, M8 Connection.
Pfeiffer Part Number: PM Z01 290 C.
This Pfeiffer normally closed venting valve is designed for the HiPace 300H turbo pumps with a TC 110 drive unit. It screws into the pump's G 1/8" (BSPP) vent port and includes a sealing ring.
The valve provides controlled, automatic venting after pump shutdown or in the event of a power failure. It limits an uncontrolled pressure rise above the permissible maximum of 15 hPa/s, helping prevent damage to the pump's rotor and magnetic bearing.
The valve has an M8 electrical connector that plugs into an accessory port on 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.
Valve activation is user-configured and supported through a Pfeiffer OmniControl 200 or DCU 110 controller, or externally via RS485. This venting valve has Pfeiffer part number PM Z01 290 C.
