There are two main reasons for the passivity of Shiyan pneumatic ball valve production market in China: first, there is still a gap between domestic pneumatic ball valves and imported products, and the quality needs to be improved; Second, some users have a weak sense of localization, and even set artificial thresholds, making it difficult for domestic enterprises to win the bid when competing with foreign enterprises. Pneumatic ball valve is a new product for connecting pumps, valves and other equipment with pipelines. They are connected by full bolts to make them a whole with a certain displacement, so that they can be adjusted according to the on-site installation size during installation and maintenance, and the axial thrust can be transmitted to the whole pipeline during operation.
This not only improves the working efficiency, but also protects the pumps, valves and other equipment. All kinds of valves produced by Chinese enterprises at present generally have such shortcomings as external leakage, internal leakage, low appearance quality, short service life, inflexible operation, and unreliable valve electric and pneumatic devices. Some products are only equivalent to the international level in the early 1980s. Therefore, in order to develop the valve industry, it is urgent to develop new products with high technology content. The pneumatic ball valve industry should vigorously adopt international standards and foreign advanced standards, strictly implement the existing national standards, and reform the existing products so that the updated products can reach the international level of the 1990s. The future market of valves will be mainly in the power industry, petrochemical industry, fertilizer, environmental protection, urban construction and other industries. Whoever has good technology, excellent quality, and continuous development of new products, pneumatic ball valve manufacturers will be able to take the lead and stand out in the fierce market competition.
