Oil field valve (3)

An important part of the oil field valve valve, used for transmission, the executive body or the handle, the following directly drive the spool to move or rotate, in order to achieve the valve switch valve or the role of regulation.
Oil field valve in the valve opening and closing process not only moving parts, mechanical parts, but also a seal. At the same time, it is subjected to the impact of the media and corrosion, but also with the filler friction. Therefore, when selecting the valve material, it must ensure that it has sufficient strength, good impact toughness, abrasion resistance and corrosion resistance. Oil field valve is a vulnerable part, in the selection of materials should pay attention to the mechanical processing and heat treatment performance. No Information No Information No Information
