2. Functions & Features
It controls the intake stroke of the cylinder. When opened, it draws in air-fuel mixture or fresh air; when closed, it seals the combustion chamber.
The valve can withstand long-term high temperature, high pressure and reciprocating impact loads, suitable for continuous operation of the unit.
3. Common Failures & Replacement
Common issues: Valve head wear, ablation, carbon deposit, valve stem scoring and poor sealing, which will lead to power reduction, abnormal exhaust and increased fuel consumption.
Replacement Interval: Inspect and replace during major overhaul every 8000–10000 operating hours under normal operation.
4. Installation Instructions
Thoroughly clean carbon deposits and dirt on valves, valve seats and guides before installation.
Check valve clearance. Standard intake valve clearance: 0.30–0.35 mm.
Ensure full seating of the valve without air leakage.
Apply special lubricant during assembly to prevent valve stem sticking.
