under the feeding valve on a fair and exhibition type two kinds. Compared with ordinary exhibition type feeding valve valve structure under no bigger difference, the exhibition type has bigger difference. On exhibition type feeding valve is referring to the relevant standards of the United States and Germany, scientific structure, sealing high reliability. Especially for materials with deposit, can avoid the material liquid in mouth parts deposition, agglomerate, formation flow corner and feeding difficulties. Although on 99 type feeding valve price is higher, but in terms of reliability is worth it.

feeding valve products are widely used in petroleum, chemical, electric power, chemical fertilizer, metallurgy, pharmacy, food, petrochemical, steam boiler, water treatment equipment imported form a complete set of device of the valve.

feeding valve sales market:

feeding valve products sold throughout the country, and exported to the Middle East, southeast Asia, Europe and the United States and other more than 10 countries and regions.

at present, in the feeding valve industry is still in a lot of form a complete set of Industrial Valves 79 target, part of the production enterprises in order to reduce the production cost, churning out, cut corners, whether it is a mark on 79 type or the exhibition type feeding valve, the metal on the orifice plate is only a thin layer of F4 or F46 cladding layer. Due to deformation of the head and stem when burnt, lead to valve head and the differential anastomotic orifice, such thin coating layer can not ensure the valve head fit closely with orifice plate, due to the closure, the operator will tighten valve hard, cause the orifice of cladding layer in a very short period of time from crack, crack. Some new valve didn't even not seal. Most users have no awareness of the valve leak test and equipment, if the valve leakage, added to the material haven't reaction reaction tank into the downstream equipment, seriously affecting the quality of the product. The leakage is the internal leakage, found no, the quality of the products is unqualified due to valve leakage is not easy to find. Therefore, this web site to inform the user that glass lining valves quality problem is more, it is necessary to choose quality reliable products.

feeding valve areas of application:

the valve is used to control fluid flow, pressure and flow of the device. Controlled fluid can be a liquid, gas, gas liquid mixture or solid-liquid mixture.

feeding valve by valve body, valve cover, seat, usually open-close part, driving mechanism, seal and fasteners, etc. Depend on the control function of the valve drive mechanism or fluid driven by opening and closing a lifting, sliding, rotary pendulum or rotary movement to change the size of the port area.

the purpose of the feeding valve is very extensive, it has close relation with People's Daily lives, such as tap water works faucet, liquefied petroleum gas stove with a pressure reducing valve is a valve. and all kinds of mechanical equipment such as internal combustion engine, steam engine, compressor, pump, pneumatic actuator, hydraulic actuator, vehicles, ships and aircraft in the indispensable components.
