Specializing in used and new surplus vacuum equipment and components.

This is a "new old stock" Pfeiffer TSF 012 turbo pump venting valve with G 1/8" port and Quattro seal. Our price: $250 As received by us, this valve had a protective cap in place on the G 1/8" port as shown. It is immaculate, and appears to never have been installed on a system. It  was supplied as part of a kit from Pfeiffer in a reclosable plastic bag with instructions and the 3-meter length of cable shown in the first picture. When used with an appropriate combination of Pfeiffer turbomolecular vacuum pump and controller, this valve can effect automatic venting of the pump during run-down (either intentional or through loss of AC mains power). Venting on such a system does not take place immediately. Instead, it is delayed until the pump has slowed to a particular range of rotational speed - a kinder, gentler venting. If you are in doubt about whether this valve should be compatible with your pump and controller, then please feel free to contact us. We may be able to assist you.
