Describe

Forged steel gate valves are available in three bonnet designs. The first is a bolted bonnet. Valves designed in this design are connected to the bonnet by bolts and nuts, and wound gaskets (made of 316 clips made of flexible graphite). Sealing. Customers can also use metal ring connection when they have special requirements. The second design form is welded valve cover. According to this design, the valve body and the valve cover are threaded and fully welded. The customer has special The through-welding connection can also be used when required. The third type is a self-sealing bonnet. The valve designed according to this design form has a valve body and a bonnet threaded connection, and the internal pressure is sealed by a self-sealing ring.
