By drive points: (1) manual valve: by human handwheel, handle, lever, sprocket drive valve. When the valve opening and closing torque is large, you can set or worm gear reducer between the handwheel and valve stem. When necessary, Jiangxi valves, can also be remotely operated or drive shaft universal joints. (2) power driven valve: use of various energy sources to drive, including: electric valves, pneumatic valves, hydraulic valves, solenoid valves, the gas-liquid interlocking the like. (3) automatic valve: automatic valve driving force is not required, but the use of the medium itself energy to actuate the valve. Why desalination water medium using rubber lined butterfly valve, fluorine diaphragm short life? Desalination of water medium containing low concentrations of acid or base, they have more corrosive to rubber. Rubber corrosion performance expansion, aging, low intensity, valve manufacturers, with rubber lined butterfly valve, diaphragm use results are poor, its essence is caused by rubber impatient corrosion. Hilltop after rubber lined diaphragm valve believe improve the corrosion resistance can be good lined diaphragm valves, but lined diaphragm membrane then stand up and down to collapse were broken off, valve plant, resulting in mechanical damage, valves shorter life expectancy. Now the best way to deal with specific water valve, it can use to 5 to 8 years. Pneumatic valves, Jiangxi valve, the valve out of Hong Kong, the Hong Kong valve provided by the Dongguan Science and Technology Co., Ltd. Valve Co., Ltd., Dongguan Ming Kong (www.gdmgfm.com) strong, credible, butterfly and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead valve and you work out of Hong Kong into the brilliant, for a better future!
