Traditional ball valve manufacturers in the development of a few years ago has been in a relatively flat period. From the manufacturing process, forged steel ball compared to stainless steel ball valve manufacturing technology will be slightly backward; and in the overseas output, forged steel ball valve annual output in 3 foreign Chinese hundreds of millions of dollars, and stainless steel ball valve can reach as high as 5 millions of dollars.
Forged steel ball valve is divided into low pressure forged steel ball valve, high pressure forged steel ball valve. High pressure forged steel ball valve according to the needs of users, in order to meet the curing environment in sulfide cracking application requirements, this series of high pressure forged steel ball from design, material selection, manufacturing, testing, surface treatment and painting are in strict accordance with the NACE standard requirements of corrosion engineers. Series ball valve is not only a wide range of material and the inner part of the material with a surface nickel plating 316 material, the sealing ring using a special polymeric material. The valve not only anti corrosion, anti sulfur ability, fire prevention, anti-static, good sealing performance, the use of a wide range of pressure and temperature, full size and reduced diameter are available, and can be equipped with multiple driving devices, chemical industry, petroleum refining torch,
The valve chamber and the stagnation of the medium due to temperature changes and people often boost, medium pressure to push the seat out of the sphere to the effect of automatic pressure relief, pressure relief valve seat after automatic reset of natural gas transportation system with the ideal valve selection.
High quality characteristics and characteristics of the scope of application of forged steel high-pressure ball valve in the future changes in the valve market occupies an important leading position. Professionals predict that in the next 3-5 years, is expected in 2025 will occupy the traditional forging steel ball valve valve industry, the market share of 70-80%, new type of forging steel ball valve will continue to emerge, even in the domestic and foreign output ahead of the other ball valve products.
