For the disassembled parts, it is recommended to replace the seals such as the valve seat and valve cover gasket with the spare parts package, and then assemble in the reverse order of disassembly. When reorganizing, pay attention to the specified torque, cross-lock the flange connecting bolts and the valve stem nut. After installing the actuator, input the corresponding signal to drive the valve core to rotate by rotating the valve stem to make the valve open and close. In addition, pay attention to maintenance and maintenance during the use process, which can better prolong its service life and reduce the occurrence of problems.
Recently, in order to reduce the operating torque of copper valves and increase the reliability of sealing, oil-sealed ball valves have appeared, in which special oil is injected between the sealing surfaces to form an oil film, which improves sealing performance and reduces operation.
