Engine valve

Engine valves are mechanical components used in internal combustion engines to allow or restrict the flow of fluid or gas to and from the combustion chambers or cylinders during engine operation. ... More information concerning other about other valve types may be found in our related guide Understanding Valves.


How do valves work in a engine? In theory, the valve operation is very simple: the cam pushes the valves down into the cylinder against the spring, opening the valve so gases can flow and then lets the valve shut under the force of the spring. The pressure in the combustion chamber rather neatly helps seal the valve shut.

1D Engine valve OEM:1-12551-050-0 for engine  6BD1
1D Engine valve OEM:1-12551-050-0 for engine 6BD1
Advantages of 1D brand Engine valve:1.Mechanical and physical properties better than conventional iron-based austenitic stainless steel alloys and comparable to nickel-based superalloys2.Better seat wear resistance than conventional alloys without adding seat facing3.Same acid corrosion resistance at lower cost than nickel-based superalloys for EGR-type diesel engines4.Up to 40% lower nickel content compared to nickel-based superalloys5.Lower nickel content reduces impact of market price fluctuation
1D Engine valve OEM:5-12551-006-0 for engine  4BC1
1D Engine valve OEM:5-12551-006-0 for engine 4BC1
Advantages of 1D brand Engine valve:1.These valves are simple in construction and are silent in operation.2.The 1D valve adopts advanced Japanese technology, and the cone surface is integrally formed, which is smooth and flat, and has strong sealing performance. Ordinary valve material is poor, the process is not up to standard, cracks, scratches, chrysanthemum patterns are prone to occur, the sealing effect is not up to standard, and the performance is poor.3.Surface nitriding treatment to increase the wear resistance, surface hardness, fatigue limit and erosion resistance the valves.
1D Engine valve OEM:8-94247875-0 for engine 4JA1
1D Engine valve OEM:8-94247875-0 for engine 4JA1
Advantages of 1D brand Engine valve:1.The intake valve of the 1D is integrally formed with a martensitic heat-resistant steel rod. The exhaust valve is welded with martensitic and austenitic alloys through friction welding, which is of high quality and stability. Reduce costs while ensuring product quality.2.The 1D valve is treated with a special special chrome plating process, which has high wear resistance, and the surface is nitrided to increase the wear resistance, surface hardness, fatigue limit and corrosion resistance of the valve.
1D Engine valve OEM:6D16T/IN for engine 6D16T
1D Engine valve OEM:6D16T/IN for engine 6D16T
Advantages of 1D brand Engine valve:1.These valves are simple in construction and are silent in operation.2.There is noise because there are no noise-making parts like valve cams, rocker arm, tappets valves, etc.3.Sleeve valve has less tendency of detonation. Cooling is very effective as the valve is in contact with water jackets.
1D Engine valve OEM:ME031937 for engine 6D16
1D Engine valve OEM:ME031937 for engine 6D16
Advantages of 1D brand Engine valve:1.The 1D valve is made of horse-type heat-resistant steel rod, and the conical surface is quenched, which has high wear resistance and corrosion resistance. Ordinary valves are generally made of alloy steel (chromium steel, nickel-chromium steel, silicon-chromium steel) and other materials, which have poor wear resistance and short service life.2.The 1D valve is treated with a special special chrome plating process, which has high wear resistance, and the surface is nitrided to increase the wear resistance, surface hardness, fatigue limit and corrosion resistance of the valve.
1D Engine valve OEM:31304-00100 for engine 4DR5
1D Engine valve OEM:31304-00100 for engine 4DR5
Advantages of 1D brand Engine valve:1.1D engine valve is made of high-quality alloy diamond friction welding of martensite and austenite by advanced Japanese equipment.2.High wear resistance and corrosion resistance in factory price.
