Vacuum Valve Specifications and Compatible Tools
Key specs: operating pressure range (10⁻⁹ to 10⁻³ Torr), flow conductance (12–45 L/s), 24V DC solenoid, and stainless-steel body (316L). Compatible with:
- VAT-3000 Series (2015–2018)
- MDC-VG4500 (2017–2020)
- HVA-Isol8-10 (2016–2019)

What to Check Before Buying a Used Vacuum Valve in 2026
- Leak rate: Test with a helium mass spectrometer; reject if >1×10⁻⁸ mbar·L/s.
- Actuator response time: Measure with a digital oscilloscope; must close within 0.8–1.2 seconds at 24V.
- Valve seat wear: Use a micrometer to check seat flatness; >0.001" deformation invalidates UHV seal.
- Coil resistance: Read with a multimeter; 2.5–3.2kΩ is acceptable. Outliers indicate insulation degradation.
- Age: Valves >10 years old require full rebuild (seals, springs, O-rings) unless original maintenance logs show <200,000 cycles.
FAQ
Q: Used vs refurbished vacuum valve—what’s the difference?
A: Used parts are resold as-is; refurbished units include new seals, recalibrated actuators, and leak testing.
Q: How to test a vacuum valve for microleaks?
A: Use a helium sniffer leak detector with a sensitivity of 1×10⁻¹⁰ mbar·L/s. Apply soapy water to O-ring grooves for visual bubble checks.
Q: Compatible with Lam Research Endura P820?
A: Yes, with a custom VAT-Flange-Ad
