Description
CTI-Cryogenics 8044047 Helix Purge Valve Electric Solenoid 110-120VAC Cryopump
The CTI-Cryogenics 8044047 is an electric solenoid purge valve from the Helix series, designed for use in CTI-Cryogenics cryopump systems. It operates on 110-120VAC at 50-60Hz, drawing 10 watts, and controls the gas purge cycle that is a critical part of cryopump regeneration and warm-up procedures.

Applications
The CTI-Cryogenics Helix series cryopumps are widely used in semiconductor fabrication, physical vapor deposition (PVD), sputtering, electron beam evaporation, and other high-vacuum process equipment. The purge valve solenoid controls the controlled admission of warm dry nitrogen (or similar purge gas) into the cryopump cold head during the regeneration cycle — the process by which cryogenically trapped gases and water vapor are periodically released and exhausted to restore the pump's cryogenic surfaces to full pumping capacity. A failed or leaking purge valve solenoid is one of the more common service items on Helix cryopumps, making replacement units like this one a practical maintenance spare for semiconductor tool operators and vacuum system service technicians. This part is compatible with CTI-Cryogenics Helix series cryopumps that use the 110-120VAC purge valve configuration.
This CTI-Cryogenics 8044047 Helix Purge Valve electric solenoid has been inspected and appears to be in good used condition. The stainless steel valve body and solenoid coil show normal wear consistent with prior service use. The 3-pin connector and wire harness are intact, and a protective cap is in place on one port.
