The design of the pneumatic valve gate form?

according to the form design of pneumatic valves, forged steel gate there are three kinds of pneumatic valve pneumatic valve cover design form. The first is a bolt type pneumatic valve cover. The pneumatic valve body and bonnet bolting, spiral wound gasket ( Clamp flexible graphite manufacturing or use a metal ring joint sealing. The second design form is welding type pneumatic valve cover, in the form of the design of pneumatic valves, the pneumatic valve body and valve cover with threaded connections, all-welded seal. When customers have special requirements, also can be used all through welding connection. Pressure self-tightening type pneumatic valve cover, for a third, according to the form design of pneumatic valve, pneumatic valve and pneumatic valve cover with threaded connections, internal pressure sealing ring seal.
