The whole world is confronted with energy shortage. Meanwhile, China is undergoing industrialization and urbanization, and its energy demand will keep rising, making the contradiction between energy supply and demand increasingly prominent. As conventional oil and gas resources grow tighter, new energy industries are expanding rapidly. It can be expected that valve applications in clean new‑energy sectors will achieve fast growth, and valve demands from clean new‑energy fields will serve as a new driving force for the future valve market.
