Cast steel gate valve
Cast steel gate valve is that valve's parts(body,bonnet etc) are made of castings metal steel materials. According to the material, there are: carbon steel gate valve, stainless steel gate valve, low alloy steel gate valve (high temperature resistant chrome molybdenum steel belongs to this category), low temperature steel gate valve and so on.
Features include low fluid resistance, wide applicable pressure, wide temperature range, labor saving for opening and closing, and medium not affected by flow direction. The structure is compact, the design is reasonable, the valve has good rigidity, the channel is smooth, and the flow resistance coefficient is small. The sealing surface is stainless steel or cemented carbide, with long service life. Use asbestos graphite or flexible graphite, reliable sealing, light and flexible operation. Various piping flange standards and flange sealing surface forms can be adopted to meet various engineering needs and user requirements.
