The processing of brass check valves consists of the following steps: Brass round rod machining: First of all, the brass round rod needs to be cut to the required length and processed on the lathe to make it into the basic shape of the return valve. Opening: Drill the required holes in the brass round rod. Under normal circumstances, the size and number of holes are determined according to the size of the valve outlet. Process the spool: Machine another brass round rod into the shape of the spool. The spool is an important part of the position that affects the opening and closing of the valve. Docking: Insert the spool into the main body of the check valve, and through certain technical operations, it is fixed together with the excuse slot. Surface treatment: Surface treatment of the check valve with sand belt or other technical means to give it a bright metal surface. Inspection: Strict quality inspection is carried out to ensure that the brass check valve meets the manufacturing requirements of customer requirements and national standards.
