Valve Spring

Key Characteristics:

• Material: High-carbon steel or chrome-silicon alloy

• Load Capacity: 50-150 lbs at installed height

• Frequency: Withstands 3,000+ cycles/minute

Critical Functions:

1. Valve Seating: Maintains compression seal

2. Cam Follow: Ensures precise valve timing

3. RPM Control: Prevents valve bounce up to redline

Technical Specifications:

• Wire diameter: 2-5mm

• Spring rate: 300-600 lbs/inch

• Operating temp: Up to 200°C

Failure Consequences:

• Broken coils causing catastrophic engine damage

• Fatigue leading to valve float

• Heat-induced spring force reduction

Performance variants include:

• Progressive-wound springs

• Titanium alloys for racing

• Dual/triple spring configurations

This unsung hero enables modern engines to achieve both high-RPM power and reliable operation.
