There are three types of valve cover designs for double forged steel globe valves The first type is bolt type valve cover, which is designed in this way. The valve body and valve cover are connected by bolts and nuts, and sealed with wrapped gaskets (made of 316 clip flexible graphite) When customers have special requirements, metal rings can also be used for connection The second design form is a welded valve cover. According to this design form, the valve body and valve cover are connected by threads and fully welded sealed When customers have special requirements, through welding connections can also be used The third type is a self sealing valve cover. Valves designed in this form have a threaded connection between the valve body and cover, and are sealed with an internal pressure self sealing ring
