The classification and features of the high pressure pneumatic ball valve

pneumatic ball valve points are: the floating ball pneumatic ball valve, pneumatic fixed ball ball valve, pneumatic valve, pneumatic valve v-shaped ball track ball, pneumatic three-way ball valve, pneumatic valve, pneumatic valve, forged steel ball stainless steel ball discharge ball pneumatic valve, resistance to sulfur pneumatic valve, pneumatic three-way ball valve, pneumatic ball valves, electric ball pneumatic valve, card sets of pneumatic valve, pneumatic valve welding ball.
by the shell/body material classification, pneumatic ball valve can be divided into:
. Metal materials pneumatic valves, pneumatic valve pneumatic valves such as carbon steel, alloy steel, stainless steel pneumatic valves, pneumatic valves, pneumatic valves, titanium alloy cast iron monel pneumatic valves, pneumatic valves, copper alloy aluminum alloy, lead alloy pneumatic valve pneumatic valve, etc.
　　. Metal lining pneumatic valve pneumatic valves: such as rubber lining pneumatic valve, pneumatic valve fluorine-butterfly, lead-lined pneumatic valves, plastic lining pneumatic valves, pneumatic valves lining enamel.
　　. Non-metallic materials: pneumatic valve pneumatic valve pneumatic valves such as ceramic, glass, plastic pneumatic valves. According to the mode of connection can be divided into: thread pneumatic ball valve, pneumatic valve and plate type pneumatic ball valve flange ball.
the domestic manufacturer of pneumatic valve ball is more, connection size are not unified. The main points of the following categories:
( ） In GB/T - Pneumatic valve metal structure is given priority to the general class of length. At present domestic most pneumatic ball valve manufacturers are produced according to this standard. But this standard is not perfect, the specification is not complete, floating ball pneumatic valve nominal diameter as the biggest DN, fixed pneumatic ball valve DN maximum nominal size. According to the factory production of pneumatic valve specifications and the master data, the floating ball pneumatic valve minimum nominal diameter as the DN, minimum fixed pneumatic ball valve nominal diameter as the DN. Manufacturers of textual research, the connection dimension is not unified, in order to have a unified standard, users in the selection and installation in the same specification can swap, suggested to GB/T - general machinery research institute The length of metal structure of pneumatic valve to revise. Recommended design institute and the user according to the standard selection, pneumatic ball valve manufacturers design and manufacture according to the standard.
