High-Temperature Alloy Steel Construction: The BY612630050002 valve is forged from heat-resistant austenitic steel or similar high-grade alloy, providing exceptional strength and creep resistance at temperatures exceeding 800°C in the exhaust port.
Specialized Seat Face Hardfacing: Features a stellite or nickel-based alloy weld deposit on the valve seat face, dramatically increasing resistance to wear, corrosion, and pitting from hot, abrasive exhaust gases.
Nitro-Carburized Stem for Enhanced Wear Life: The valve stem undergoes a nitro-carburizing surface treatment, creating a hard, wear-resistant layer that reduces friction in the guide and prevents stem scuffing.
Hollow Stem with Sodium Filling (if applicable): For ultra-high-performance applications, the BY612630050002 may feature a hollow stem partially filled with sodium, which melts to transfer heat from the valve head to the stem, improving cooling.

The BY612630050002 exhaust valve is a critical component in the four-stroke cycle of a SHACMAN diesel engine. It is located in the cylinder head and opens to allow the expulsion of spent combustion gases.
This process is essential for clearing the cylinder to make way for a fresh charge of air. Efficient exhaust gas scavenging directly impacts the engine’s volumetric efficiency and power output.
The valve must seal perfectly when closed to maintain compression during the compression and power strokes. A leaky BY612630050002 valve can cause a significant drop in cylinder pressure.
This leads to power loss, increased fuel consumption, and potential overheating of the valve itself. In turbocharged engines, the exhaust valve also plays a key role in driving the turbine.
The durability of the BY612630050002 is tested by extreme thermal cycling and exposure to corrosive compounds in the exhaust stream. Its performance is linked to emission control system efficiency.
Properly functioning exhaust valves are crucial for meeting modern emission regulations. They help ensure complete combustion and effective operation of after-treatment devices.
1. Ensure the engine is cool and the cylinder head is properly secured on a clean workbench. Always work in a clean environment.
2. Lubricate the stem of the new BY612630050002 valve lightly with clean engine oil specified for assembly. Ensure the valve guide is clean and within wear limits.
3. Carefully insert the valve into its designated guide in the cylinder head. Use a valve spring compressor to install the valve spring, retainer, and keepers.
4. After installing all valves, perform a valve lapping procedure if recommended by the manufacturer to ensure a perfect seat contact pattern for the BY612630050002.
5. Set the valve clearance (lash) to the precise specification for your SHACMAN engine model using feeler gauges. This is critical for thermal expansion and noise control.
6. Reassemble the rocker arm assembly, camshaft, and other related components according to the factory service manual torque sequences and values.
7. After assembly, rotate the engine by hand to ensure no interference exists before starting. Conduct a compression test to verify sealing integrity.
• Inspect the BY612630050002 valves during every major engine overhaul or cylinder head service for signs of wear, burning, or cracking.
• Measure valve stem diameter and length for wear and stretching. Check the valve head for thickness reduction due to re-facing.
• Examine the seat face for pitting, grooves, or wear. The hardfacing on the BY612630050002 should be intact without significant erosion.
• Clean carbon deposits from the valve head and stem gently without scratching the surfaces. Use appropriate solvents and tools.
• Always replace valves in complete sets per cylinder or as recommended to maintain balanced performance. Keep a log of valve replacements.
• Ensure the engine cooling and lubrication systems are functioning optimally to extend the service life of the BY612630050002 valves.
Proper valve clearance adjustment is non-negotiable. Incorrect lash can cause valve train damage, poor performance, and premature failure of the BY612630050002.
Choosing the genuine BY612630050002 valve guarantees material composition that matches the original engine design specifications. It is formulated to withstand specific thermal and mechanical stresses.
