How Much Does a Used MKS 253 Butterfly Valve Cost in 2026?

In 2026, used MKS 253 Butterfly Valves (part number 253-001) range from $1,430 to $4,900, depending on condition and calibration history. Refurbished units with OEM seals and recertified actuators typically fall between $3,500–$4,900, while untested used parts start at $1,430–$3,200. Compared to new units (priced ~$15,000–$18,000 in 2026), used parts offer ~70–90% savings. Critical caveat: valves older than 15 years (pre-2008 manufacture) often require seal replacement due to elastomer degradation, adding $300–$600 in labor costs. Always verify vacuum integrity ratings (≤1×10⁻⁵ Torr) and actuator response time (<1.2 seconds) before purchase.

MKS 253 Butterfly Valve Specifications and Compatible Tools

The MKS 253 features a 2.5" port size, max vacuum rating of 1×10⁻⁵ Torr, and flow capacity up to 500 sccm. It operates on 24V DC with a 50/60Hz actuator cycle. Compatible tools include:

AMAT Centura 7200 (1998–2005)
Lam Research P5i Etcher (2001–2009)
Tokyo Electron Lambda Genesis (2000–2007)
Varian 8920 Cluster Tool (1999–2004)
Exclusion warning: Not compatible with Axcelis 300mm PVD systems (part number 745-2212-01) due to mismatched port threading (NPT vs. ISO-K). Verify tool’s vacuum manifold specs before installation.

What to Check Before Buying a Used MKS 253 Butterfly Valve in 2026

Seat-to-disc alignment: Use a dial gauge to measure runout; reject if >0.001".
Actuator voltage draw: Test with a multimeter; 24V DC units must operate within 22.5–25.5V under load.
Seal hardness: Check O-rings with a durometer; 85–95 Shore A is standard. <80A indicates aging.
Cycle count: Valves with >500,000 actuations (typical in 2010+ tools) require stem bearing inspection.
