Edwards 1850 Vacuum Valve Specifications and Compatible Tools

Key specs: 24V DC operation, 1.5A max current, 100 SCCM flow capacity, and a max pressure differential of 10⁶ Torr. Compatible with Applied Materials Centura P5500 (2003–2008), Lam Research Endura 5500 (2004–2010), and Kokusai Electric F-5000 (2002–2007). Exclusion warning: Do not install on Varian 300mm PVT chambers (P/N 789-1234)—the 1850’s solenoid design conflicts with Varian’s pressure feedback loop. Cross-check tool’s vacuum subsystem schematic for port threading (NPT vs. ISO-KF).

What to Check Before Buying a Used Edwards 1850 Vacuum Valve in 2026

Leak test with helium mass spectrometer: Acceptable leak rate <1×10⁻⁹ mbar·L/s.
Actuation time: Measure response using a digital oscilloscope; >500ms delay indicates coil degradation.
Seal integrity: Inspect Viton O-rings for cracks; reject if surface hardness exceeds 85 Shore A (use durometer).
Manufacture date: Units produced pre-2015 use an epoxy formulation prone to delamination under >150°C.
Wiring harness: Verify continuity with a multimeter; resistance >0.5Ω signals internal arcing risk.
