| Abstract: | The EPC process for body of gate valve with soft sealing was analyzed. The main technological parameters, including pattern making, molding and pouring, were presented. The production practice shows that the valve casings produced by EPC process have smooth surface and accurate dimensions. Compared with sand mold process, the weight-reducing of EPC is to 62.5%. Therefore, the drilling hours are shortened, the production cost is reduced, and the economic benefit is imoroved. |
