Traditionally, valve insets were made of cast iron. Recent advancements in powder metal technology, on the other hand, have enabled manufacturers such as Dura-Bond to build valve seats with greater heat resistance.

Powder metal valve insets are available from Dura-Bond in a variety of styles. Alloys with copper wafer infiltration, copper-based metal, and abrasion-resistant valves are examples of these. These materials are suited for high-temperature and high-wear applications.

The valve seat inserts of the Dura-Bond "70000 Diamond Series" are constructed of a high temperature mixture of tool steel and tungsten carbide. They also have a tempered martensitic matrix, which provides high temperature lubrication.

Dura-Bond powder metal valve insets are engineered for great heat resistance, reduced wear, and easy machining. They comprise finely distributed tungsten carbide and iron particles from a unique alloy. These particles facilitate the cutting of the valve seat insert.

  • SPM(tm) EdgeX

    SPM(tm) EdgeX

    The SPM(tm) EdgeX Valve features a carbide seat and a patented urethane head to optimize fluid dynamics. The combination provides greater washout resistance, increased durability, and reduced maintenance time.

    SPM Oil & Gas's SPM(tm) EdgeX Valve is a cutting-edge product. With the company's patented tungsten carbide inserts technology, this high performance valve has the longest life of any valve in its class. The EdgeX(tm) Valve is designed to outlast traditional steel seats by a factor of two, with a lifespan of up to 680 hours of operation. The EdgeX(tm) Valve has a strike angle of 30 degrees and is interchangeable with any standard taper fluid end. The SPM(tm) Valve is also extremely versatile and simple to use.

  • PEP


    PEP, in addition to being one of the major makers of engine components in the United States, has a knack for innovation. For their inventions, they have received various honors. Their products are widely used in industrial engines and even in the automotive industry.

    PEP tungsten carbide Valve insets in Valve are produced from a unique tungsten carbide alloy formulation. As a result, at exhaust valve seat operating temperatures, the material is thermally stable. They can also tolerate the stresses of gas treatment operations. They also come in a variety of materials, ranging from basic compression fittings to thermoplastic tubing.

    The PEP M2 is the tiniest of the bunch. It's an unique tungsten carbide alloy inlay that hardens within the first few kilometers. There is also a black rubber body seal. It is also constructed from the greatest materials available for the purpose. 

  • Copper-infiltrated


    Alloys A and B are common alloys utilized in the production of copper-infiltrated valve insets. These alloys have a high thermal conductivity and a low wear rate. They also provide better heat transfer from the valve head to the water-cooled engine head. They're also lubricating. They are appropriate for use in high-temperature engines.

    Furthermore, the material has outstanding wear resistance at both low and high temperatures. The strong heat conductivity also helps to keep the valve seat insert cool.

    The material also has a microstructure of equally distributed metal alloy oxides. When exposed to high temperatures, the oxides behave similarly to ceramics in that they do not soften or disintegrate. They also keep the metal's machinability. The oxides also help to improve wear resistance.

Cemented carbide

Tungsten carbide plate is harder and more wear resistant than stainless steel. It is employed in structural components such as boring bars, plungers, and powder compacting dies, in addition to cutting instruments. It is also used to make molds for cell phone electrical parts.

Carbide was used to cut metal during WWII. This prompted machine tool manufacturers to enhance spindle bearings, feeds, and cutting speeds. Carbide Inserts are common in modern face mills and lathes.

Cemented carbide is a composite material made up of a metallic binder that holds together hard carbide particles. Aside from being a traditional refractory, the metal binder is also extremely ductile, resulting in a high overall toughness.

Cemented Carbide's main strength, in terms of the most well-known qualities, is its hardness. It also has good wear resistance, thermal stability, and a low melting point. It also has excellent abrasive characteristics.
