Speaking of a new type of valve is widely used in recent years, are going to have to mention pneumatic ball valve, pneumatic ball Industrial Valves is assembled on the ball valves, pneumatic actuators in practical application as the control of flow direction of medium in the pipeline valve, let's say how to buy pneumatic valve selection. A, according to the working condition selection of medium temperature is critical, some pneumatic ball valve is suitable for the processing hot fluid some suitable for treatment of cold fluid, different application of pneumatic ball valve made by different materials, ceramic, stainless steel metal materials and PVC plastic, pneumatic ball valve to clear when the choose and buy your actual demand, and product application environment. Second, according to the working pressure type selection in pneumatic valve closing, will bear the pressure from pipeline medium concentration produces, so when buying pneumatic ball valve selection, to determine valve work requires pressure range, then select the corresponding specification. Three, according to the dielectric fluid is diverse selection of the actual needs of customers, some buy pneumatic ball Industrial Valves is used for dealing with common flow of water, such as applied to the hydraulic power plants, while others need to use to control chemical medium flow, even radioactive material, this requires a different fluid flow control system is designed pneumatic ball valve. Four, according to the price selection if buy ball valves are not sure what good choice model, it is easy to waste shouldn't spend money, because the price of the pneumatic ball valve is also related to the specifications. Specialized production and sales of industrial application Industrial Valves of enterprises on the market a lot, but the quality is good and bad, light to find cheaper pneumatic ball valve is easier to suffer, because the quality really is particularly bad, so be sure to combine the above these points. Here is a brief explanation of pneumatic ball valve operating right way. Pneumatic ball valve operation method: 1, the pneumatic valves open and close direction of operation, all should be clockwise closing. 2, as the pneumatic valve in the pipeline, often artificial opening and closing, opening and closing of revolution shoulds not be too much, is the large diameter valves also should be 200 - 600 RPM. 3, in order to facilitate a person's opening and closing operation, the plumber pressure conditions, the largest open-close torque appropriate for n - 240 m。 4, pneumatic valve opening and closing operation side should be square tenon, standard and size, and face to the ground, so that people can be directly from the ground. Valves shall not apply to the underground pipe network with roulette. 5, pneumatic valve opening and closing degree of display panel: 1) the degree of pneumatic valve opening and closing scale line, cover should be cast in the transmission or conversion direction after the show plate shell, all face to the ground, scale line brush on phosphor powder, as a prominent; (2) of the dial needle material under the condition of management better available stainless steel plate, or paint for steel plate, do not use the aluminum skin production; (3) dial needle striking, fixation, once the open-close adjustment accurately, the rivet lock. If, pneumatic valve buried deep, operating mechanism and display plate distance from the ground 1 or more. 5 m, should be equipped with facilities of extension rod, and fixed firmly in mind, so that people from the face of the earth observation and operation. That is to say, the valve opening and closing operation in pipe network, unfavorable under operation. This article by all standing valve technology and news editing and publishing
