Hydraulic control valves are imported from Taiwan to China late nineties, the earliest use in some countries, the agricultural irrigation systems, mass production in Israel, the Netherlands, Denmark and other European countries, and later developed into the United States, Canada and Asia and other places, and in the Xu things outside the field in addition to irrigation has been widely used and developed. I produced a series of wide hydraulic control valve well in domestic and foreign construction, fire, municipal, power, pipeline and other systems have performance.
Hydraulic control valve on the use of major works, chamber pressure differential control valve disc movement, and then to achieve different purposes through the bypass line and the wide variety of different connection guide. At present, such valves have been derived abroad hundreds of uses, and only a dozen domestic development, and are used at room temperature, low pressure, physical and chemical properties similar to water media. For example: remote control float valve, valves, slow closing check valve, flow control valve inside, holding pressure relief valves, electric valves, pumps and control valves, pressure balance valve, emergency shut-off valve, water valve and so on. If a breakthrough in the selection, such valves can also be used in the temperature, medium or high corrosive pipe.
I plant since the production of hydraulic control valves since, constantly listen to user comments and suggestions, learn the essence of foreign products, based on the initial product again improved from the structure, selection, processing and other aspects, such products have been widely used at present the major and medium-sized cities has been praised by users, the popular user-letter Le. What force control valve DN450 caliber recommend the following selection of diaphragm, 500 more than the choice of caliber piston. The following detailed description of its own characteristics.
