WJ/Z41H/Y forged steel corrugated pipe globe valveDetailed product description：

Structural features:
There are two types of valve cover designs for WJ/Z41H/Y forged steel bellows 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. Valves designed in this form have a threaded connection between the valve body and the valve cover, with a fully welded seal. When customers have special requirements, full penetration welding can also be used.
