6D170 Diesel Engine Valve Guide
The main material used for valve seats, cemented carbide, has the properties of cemented carbide, i.e. long service life and high pressure resistance, as well as the ability to withstand corrosion and wear.
The engine valve ring is made of high-quality materials that enable it to withstand high-speed shock and provide excellent sealing performance, thereby prolonging the generator’s lifespan. Additionally, the valve seat ring has a simple structure that makes it easy and convenient to perform daily maintenance and exchange when necessary.
Made of Wear-resistant Steel:
The valve seat ring is made of wear-resistant steel material that can withstand extreme environments, ensuring that it can continue to function effectively even under harsh conditions. This feature makes it a reliable and durable choice for users who need a valve seat ring that can withstand heavy use and provide long-term stability.
Good Flexibility and Applicability:
The valve seat ring is a highly flexible and adaptable component. It is designed to be compatible with a wide range of engine models and specifications, making it a versatile choice for anyone who needs a valve seat ring that can meet your specific requirements. Due to its advanced design and manufacturing process, plus, made of high-quality materials, enabling it to withstand high-speed shock and provide excellent sealing performance, ensuring that it can function effectively in a variety of different environments and conditions. If you do not know whether it is suitable for your generator, you can contact with us, our professionals will give you the perfect answer and suggestion.

The Notice of Valve Guides?
- Please confirm the the right type to fit your generator, if you are not sure, please contact us;
- Please make sure of the right direction to install, so that it can well seal the valves and valve seat rings;
- In using, please regularly check the extent of damage to be changed in time, so that it will not influence the normal operation;
- In changing, please use professional tools and technology to prevent the valve and valve seat ring from damage, then influencing the normal operation in generator;
- In saving and transportation, please notice the environment and pressure condition so that it will lose the function and reduce the using period.
Materials for valve seats
Cemented carbide, the main material used for valve seats, also has the properties of cemented carbide, i.e. long service life, corrosion and wear resistance and the ability to withstand high pressures.
When tungsten and carbon are combined, they become the hardest substance in tungsten carbide. When parts and equipment wear out, applying carbide to hard-surfaced materials is the quickest and easiest way to weld them.
Its versatility and flexibility in the way it is applied are unsurpassed. Chinatungsten Online offers a variety of sizes to suit different needs.
Cemented carbide hardfacing will reduce wear in a wide range of mining and processing processes such as: ore, minerals, agriculture, construction, and surface mining tools, drilling for oil and gas or horizontal directional drilling, excavation and circulation processes.
Characteristics of Cemented Valve Seats
1. Corrosion and wear resistance.
2. Longer working time.
3. Resistance to high pressure.
4. High dimensional accuracy.
5. Excellent tolerance to thrust loads and high temperatures.
6. Suitable for most passenger cars, light and heavy trucks, diesel engines, and stationary industrial engines.
7. Cast tungsten carbide piece by piece.
8. Maximum strength with minimum distortion, good resistance to severe impact, and heat dissipation. Works in all fuels.
9. Easy to work on tools and stones.
10. For easy machining, the PEP seats are softened to a hardness of R/C 42, allowing the free combination of tool and stone and faster and cleaner machining with existing tools.
11. Running in the 1400 to 1500 range.
12. PEP seats offer a higher operating range than their competitors. In today's hot running motors allow a greater margin of safety.
13. Hardening during operation.
14. During the initial working phase, the special carbide hardens. The initial "soft" phase allows the valve to reach the correct seat.
Notes on the grinding of engine valves seats
1. When the inlet and exhaust valves are paired with the valve seats they must not be interchanged.
2. Before grinding, a rubber pad with an inner diameter smaller than that of the valve stem should be set on the diesel engine valve stem, the outer diameter should be moderate, this rubber pad is to prevent grinding sand from entering the conduit with the valve stem when grinding the valve, and cause artificial abrasive wear on the valve stem and conduit hole, shortening the service life of the valve stem and conduit.
3. The valve stem is coated with diesel oil to lubricate and reduce resistance when grinding the valve.
4. Car engine valve head and valve seat taper sealing surface coated with abrasive sand, the number of appropriate and uniform, more waste, less does not work, such as abrasive sand is too dry available in a small amount of lubricant to thin.
5. Grinding force should not be too large, or too fierce, grinding gas valve, gas valve should have reciprocating motion and a small amount of rotary motion, or the use of downward pressure of the rotary grinding method.
6. If the valve seat pockmarks, pits are deep and there is no valve seat grinding machine, use the same angle reamer or the machine to replace the old valve, and make a tire tool for its initial research.
