800lb Forged Steel Extended Body Gate Valve (GAZ61H)
Product Description
There are two types of valve cover design for forged steel extended body gate valves. The first type is a bolted valve cover. Valves designed according to this design form are connected to the valve cover with bolts and nuts, and sealed with spiral wound gaskets (made of 304 flexible graphite). When customers have special requirements, metal ring connections 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 connected with threads, Full weld sealing. When customers have special requirements, penetration welding connection can also be used Extended body valves are suitable for gate, ball, and globe valves
