Shortcoming valve actuators is to construct complex, more difficult when using Valve Co., Ltd. Guangzhou Kaiheng in damp places for explosive medium Shanghai Guanlong valve Machinery Co., we need proof measures. Valve actuators driven by valve types, Z and Q can be divided into two categories. Output shaft Z type valve electric device can turn out a lot of laps, suitable for driving valve, closing valves, diaphragm valves, etc; Q output shaft type rotary valve actuators only 90. Suitable for driving plug, ball and butterfly valves. According to their type of protection are common type, flameproof (expressed in B), heat-resistant (represented by R) and triple-type (ie outdoor, corrosion, explosion, represented as S). Manual valve is a valve basic driving mode. It includes a hand wheel, lever or wrench two direct drive and driven through the transmission mechanism. When the valve start torque is large, the valve can be driven by a gear or worm gear, in order to achieve the purpose of omission. Gear sub spur gear and bevel gear drive. Gear reduction ratio, suitable for gate and globe valves, worm gear reducer relatively large for flash cocks, ball and butterfly Taiwan Toyama Valve Co. | Huizhou valves | 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!
