Z11 pressure self tightening forged steel gate valve threaded connection

Z11Y pressure self tightening forged steel gate valveIntroduction:

There are three types of valve cover designs for forged steel gate valves. *The type is a bolt type valve cover. Valves designed in this form have their valve body and 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, full soldering 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.
