H61H welded lifting forged steel check valveThere are three types of body cover connection design forms. The first type is bolt type valve cover: valves designed in this form have their valve body and valve cover 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 the pressure self tightening 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.
