Analysis of Stainless Steel Ball Valve Manufacturers

With the continuous strengthening of national macro-control policies, energy, metallurgy, chemical and other industries to reduce investment, stainless steel ball valve industry oversupply situation has emerged. Stainless steel ball valve business entered into the era of vicious price competition.

ball-valves
Statistics show that the number of stainless steel ball valve ranks first in the world, but the low level, small-scale, family workshop type enterprises occupy the majority. Because of the repeated construction, investment, technology transfer is not enough, most of our leading products of stainless steel ball valve enterprises still remain at the popular level.
The root cause of this situation industry analysts believe that although the stainless steel ball valve products in relation to electronic products, technical content is relatively low, but the reasonable matching material, process of scientific applications on the safe use of stainless steel ball valve plays a key role, which will increase the production cost of enterprises.

working-of-check-valves
At present, stainless steel ball valve industry price war intensified, in order to reduce costs, they do not consider the product material, from the immediate interests, perhaps temporarily gained market share, but in exchange for corporate reputation is lower. On the other hand, focus on the stainless steel ball valve product quality and technology investment, although the high cost of the products, the price is high, and sometimes in the market, especially the newly developed market favor, however, after the customer compared to that of high quality stainless steel ball valve products, although the one-time purchase cost is high, but overall costs are far lower than the low price of ordinary product.
In recent years, with the rapid development of economy China, the quality of stainless steel ball valves are generally improved, if the operator of manual ball valve enterprises, is still focused on the price war, do not pay attention to product quality, technical level and customer service inputs, is bound to be “God” out.
In fact, not only the stainless steel ball valve industry has entered the shuffle stage, there are many industries have entered this stage, which is every industry must go through.

Structure and Working Principle of Butterfly Valve

Structure and Working Principle of Butterfly Valve
