02010-BE24-AAM1 — Gate Valve, DN63 CF (VAT)

VAT 02010-BE24-AAM1 Specifications and Compatible Tools

Key specs: DN63 Conflat (CF-63) flange, pneumatic actuator, 1e-9 sccm He leak rate (new), <1.2 sec open/close time, 500,000 cycle MTTF with OEM bellows, <1.8A motor current (18.5Ω coil resistance).

Compatible tools:

• AMAT Centura 300mm DPS II (Platform ID: 8800-01234 Rev. F, 2001–2008)
• Lam Research 2300 Kiyo E (System ID: LAM-KIYO-E-2300-789, all PECVD configs)
• Novellus Altus Max CVD (Model: ALTUS-MAX-CVD-650 Rev. 3, 2004–2010)
• TEL Clean Track LITHIUS Pro (CT-LITHIUS-PRO-2021, coater/developer load lock)
• Hitachi High-Tech ECR Etcher (Model: ECR-4500-LL, load lock subsystem)

Critical exclusion: Not compatible with DN40 CF ports (smaller flange). DN63 and DN40 valves have different bolt patterns—forced installation cracks the valve body.

What to Check Before Buying a Used VAT 02010-BE24-AAM1 in 2026

1. Gate stem scoring: Inspect under 10x magnification. Reject if scratches >0.05mm deep—causes sticking and position sensor faults. LL-VALVE-12 alarms often trace to stem damage.

2. Seat pitting: Check CF sealing surface with feeler gauge. Any pit >0.1mm diameter disqualifies the unit. Pitted seats leak at 1e-7 sccm vs. spec 1e-9.

3. Bellows fatigue: Flex bellows manually through full stroke. Permanent creases, stiff spots, or visible weld cracks mean failure within 10,000 cycles. Walk away.

4. Motor current draw: Measure at connector pins during open/close cycle. Must be <1.8A per AMAT spec. >2.0A indicates bearing wear or mechanical binding.

5. Helium leak verification: Demand test report showing <1e-9 atm·cc/sec at bellows weld and flange seals. This is the only reliable predictor of vacuum integrity.

FAQ

Q: What's the difference between BE24-AAM1 and BE24-AAP1?
A: AAM1 = manual handwheel actuator. AAP1 = pneumatic actuator. Same valve body, different drive. Pneumatic cycles in 1.2 sec; manual takes 3.5 sec. Most 300mm tools use pneumatic (AAP1) for automated operation.

Q: Why does my Lam 2300 show VAC-LOSS-05 during pump-down?
A: This alarm indicates transfer chamber base pressure >1e-5 Torr (normal: 5e-7 Torr in 90 sec). Likely causes: valve not sealing (bellows leak), slow actuation (>1.2 sec), or CF flange contamination. Helium leak test the valve body first.

Q: Can I replace just the bellows instead of the whole valve?
A: Technically yes, but VAT bellows welding requires cleanroom conditions and specialized equipment. Field repairs achieve 1e-6 sccm leak rates—1000x worse than OEM. For production tools, replace the entire valve with refurbished unit.

Q: How do I verify a seller's "tested OK" claim?
A: Demand specific data: helium leak rate (must be <1e-9), cycle time (<1.2 sec), motor current (<1.8A), and photos of CF sealing surfaces. Vague claims without numbers = red flag.
