ball valve and gate valve
With this, compared to a gate valve opening and closing time is short, the operating torque, installation space is small and light weight characteristics, some division of labor instead of using butterfly valves. But all along, butterfly valve sealing performance did not fully meet the market requirements; in addition to the center line rubber lined butterfly valve can be in a certain way within the sealed pressure, the other basic structure is one-way flow. Midline not restricted by the popularity of rubber. Improved, the market appears flexible stainless steel sheet structure of the two-way valve, but its high price. Currently used in petroleum, natural gas, gas pipelines and other media more important, in general, the network, in particular, very little water system applications.
Jushui Brass Industry Co., Ltd., Based on years of design experience in the successful development of the most sophisticated, cost-effective new ball, the structure of semi-eccentric butterfly valve structure! Sealing principle with the front end of the fixed valve sealing and sealing force eccentric butterfly valve in order to achieve a high and low voltage bi-directional cut.
The new product also has a lot of good performance: the two seals in the sealing surface hardness according to the different needs of the use of space spraying, Ethernet laser ablation, vacuum infiltration protection of advanced technology such as the formation of complex reactor stainless steel, austenitic stainless steel, carbide, metal ceramic, synthetic diamond and other functional gradient materials. The center can automatically (adaptive), automatic wear compensation process more automatic than to be a high sealed pressure, instant off, instant no friction between the sealing open, open the valve when the ever-expanding and forward projection, structure, short, small can produce large diameter, large diameter, large diameter, large diameter valves, transportation, installation, maintenance, easy maintenance, reliable operation and a series of advantages, as the valve industry, a major technological revolution.
