stop valve(Copper, Aluminum)

1. Cut-off valve can be used for most of the media flow systems. Have been developed to meet the petrochemical, electric power, metallurgy, urban construction, chemical and other departments for various uses various forms of cut-off valve2 .The most obvious advantage of cut-off valve are: (L) in the opening and closing process, due to valve flap and valve sealing surface friction between the valve smaller than that, and therefore wear. (2) to open a high degree of general channel diameter of the valve seat is only l / 4, so much smaller than the valve. (3), usually in the valve and valve flap is only one sealing surface, thus comparison of manufacturing processes is good, easy to repair. However, the cut-off valve defects can not be ignored. Its shortcomings are mainly relatively large flow resistance coefficient, resulting in pressure loss, especially in the hydraulic device, this pressure loss is particularly evident Our company can according to customer requirements, production of various specifications and models of copper, aluminum valve products. If you are interested, you can put drawings made over, and we quote as soon as possible.
