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.
