The commonly used materials for the valve body of metal-sealed ball valves are generally WCB, CF8, CF8M, CF3, CF3M, C9, C5, C12, 310S, Monel and other materials. Metal-sealed ball valve seats can be made of carbon steel or stainless steel, carbon steel substrate surfacing stainless steel or stainless steel substrate surfacing hard alloy, etc. In order to ensure that the sealing surface of the valve seat has a certain hardness and wear resistance, the Cr13 stainless steel valve seat needs to be heat treated. Or use carbon steel or stainless steel valve seat (ball) to spray Ni60 and do cold and hot spray treatment.

The valve body is made of carbon steel, and the valve seat is made of carbon steel surfacing welding stainless steel or cold (hot) spray treatment. It is suitable for non-corrosive applications at temperatures below 425 ° C, including water, oil and gas, and media with fine particles.

The valve body is made of stainless steel (CF8, CF8M, CF3, CF3M), and the valve seat is made of stainless steel surfacing welding carbide or cold (hot) spray treatment. It is suitable for corrosive temperatures below 500°C or non-corrosive at ultra-low or high temperatures. Applications, including water, oil and gas and media with fine particles.

The valve body is made of stainless steel (C9, C5, C12), and the valve seat is made of C9, C5, C12 surfacing hard alloy or cold (hot) spray treatment. Corrosive applications, including water, oil and gas and media with fine particles.

The body of the hard-sealed ball valve is made of stainless steel (310S), and the seat is made of 310S surfacing hard alloy for cold (hot) spraying. It is suitable for high-temperature non-corrosive applications below 800 °C, including water, oil and gas, and fine particles medium.
