Ball valve came out in the 50s of the 20th century, with the rapid development of science and technology, the continuous improvement of production technology and product structure, in just 40 years, has rapidly developed into a major valve. In the industrially developed countries of the West, the use of ball valves is increasing year by year.

The butterfly valve commonly divided in to these two general types, Concentric is sealed by the rubber, according to the rubber type it can be suitable for many substances, like water, or some chemical. But it usually used in below PN 16. Eccentric butterfly valve include the double or triple eccentric/offsets, the disc achieves a “cam-like rotation” during opening and closing, completely eliminating frictional wear. Taking the triple offset structure as an example, the valve stem axis forms a compound angle with the sealing surface, ensuring zero leakage even under high temperature and high pressure conditions.

Cast steel butterfly valve: "Flow Switch" in Industrial pipelines

Core advantages: thin structure (30%~50% thinner than flange type) and with lightweight (weight reduction of 20%~40%) Necessary scenarios: it usually be used in space-constrained pipelines (equipment interlayer/renovation projects).

Recently, our company has successfully completed the production of the orders set by the customers and has successfully packed and dispatched the goods to the countries where the overseas customers are located. This batch of orders mainly includes butterfly valves and gate valves, providing services for the market where the customer is located.
