There are two types of valve cover design for vent and deluge valves. The first type is a bolted valve cover. Valves designed according to this design form are connected to the valve body with bolts and nuts, and sealed with a spiral wound gasket (made of 304 flexible graphite). When customers have special requirements, metal ring connection can also be used. The second design form is a welded valve cover. For valves designed in this design form, the valve body and valve cover are threaded and fully welded for sealing
