The road of technology creation and development of new electric ball valve products mainly includes the following. The first road is to cooperate with universities and research institutions. The new valve products jointly developed by both parties have the international leading product level, which can compete with foreign brand valve products and have the international standard. Through scientific and technological creation, the gap and distance between domestic valves and international valves can be narrowed. If the enterprise has certain scientific and technological strength, it can develop and create new products by itself.

3. Before the connection with the pipeline is prepared in advance, the residual residue in the clean pipeline must be cleaned and eliminated (this chemical will damage the high-pressure gate valve and ball
