Electro-hydraulic servo piston flow control pneumatic valve functional features, technical parameters

electro-hydraulic servo piston flow control pneumatic valve ( Also known as: pneumatic piston multi-function control valve) Widely used in precision adjustment, safety relief or adjustment, safety in one pipe system. Can be used as air dynamic field do wind tunnel testing ground pipeline flow control pneumatic valve; Also in the aspect of water can be used as a release of pneumatic valve and explosion-proof pipe pneumatic valve; In water industry can be used as a pneumatic valve, flow control can be used to put pneumatic valve, pneumatic valve or irrigation pipe net in sewage, water treatment can be used as a pump start protection pneumatic valve, or are equipped with special adjust export parts, also can be used in water treatment plant of pneumatic valve, flow control can also be used for sewage treatment plant capacity regulating pneumatic valve, piston pneumatic valve on the water supply according to the working condition of liquid in different export parts, used as a pressure/flow control pneumatic valve, such as the pipe network pressure balance.
the pneumatic valve body is mainly by the pneumatic valve, pneumatic valve, pneumatic valve seat, piston, water cage ( Blades, pneumatic valve rod, a crank, connecting rod, bushings, guide rail, piston, sealing ring of the pneumatic valve and electro-hydraulic servo hydraulic control device and the pressure sensor ( Flow meter, etc. Diameter from mm to mm, pressure levels from the PN. Kg/c ㎡ to PN. Kg/c ㎡, import and export pressure general kg/c ㎡, not only to fill the gaps of large diameter control pneumatic valve, and fill in the high pressure and large pressure difference control pneumatic valve blank.
the electro-hydraulic servo hydraulic control device is designed for a university of aeronautics and astronautics form a complete set of wind tunnel testing ground for regulating pneumatic valve design, mainly used for the opening of pneumatic valves for precise control. The electro-hydraulic servo system, this system is mainly composed of hydraulic pump station, electric control system, electro-hydraulic servo amplifier, servo hydraulic actuators. This device adopts the latest thread instrumentation pneumatic valve pneumatic valve group as the core control integration, compact structure. The overall layout is reasonable, beautiful, easy operation and installation and maintenance. Piston type multifunctional control pneumatic valve has a variety of control functions, including the functions of water level control, pressure control, check control, holding pressure, pressure control, flow control function, the broken tube closed control function and emptying reservoir drainage function, etc.
