Flange gate valve manufacturer
Flange gate valve manufacturers, for you to recommend the general Bundor valve.General valve specializes in the production of flanged gate valve, including gray cast iron, ductile iron, cast steel, stainless steel, etc.The company has a number of high-quality, experienced professional technical personnel and production team, with a series of modern production equipment and testing facilities.The products are widely used in petroleum, chemical industry, metallurgy, military industry, light textile, electric power, water power, food and other industries, deeply trusted by the majority of users.
Flange gate valve is a kind of valve widely used. It is usually used for cutting device with diameter DN≥ 50mm, and for cutting device with very small diameter, gate valve can also be used, but screw lock gate valve is usually used.
Flanged gate valves have the following advantages:
1. Small hydromechanical friction resistance, thin brush and corrosion for sealing surfaces.
2. It is easier to open and close.
3. No restriction on material inflow, no disturbance and no reduction of working pressure.
4. Simple shape, long and short structure, good production and manufacturing process performance, wide application fields.
Flanged gate valves also have disadvantages:
1. The middle of the sealing surface is easy to cause erosion and abrasion, so maintenance is difficult.
2, the size is large, must open a certain indoor space, open and close for a long time.
3. Complex structure.The type of sluice can be divided into wedge type sluice valve and parallel type sluice valve according to the sealing surface, and wedge type sluice valve can be divided into single type sluice valve, double type sluice valve and ductile type sluice valve.Parallel face gate valves can be divided into single gate type and double gate type.According to the seat of the external thread location division, can be divided into dark stem gate valve and open stem gate valve two.
