Pneumatic steam regulating valve manufacturers can be seen everywhere in our lives. Many companies use valves. When choosing a valve, we must choose a pneumatic steam regulating valve from various perspectives. The following are the precautions for purchasing a pneumatic steam regulating valve. , From these perspectives, you can buy a more cost-effective control valve. (1): Adjustment function of pneumatic steam regulating valve ①: The valve is required to operate smoothly; ②: Small opening degree has good adjustment performance; ③: Select the required flow characteristics; ④: Meet the adjustable ratio; ⑤: The resistance is small and the flow rate is less ratio (the ratio of the rated flow parameter of the valve to the nominal diameter); ⑥: regulating speed.
(2): Whether the pneumatic steam regulating valve is anti-blocking even if it is a clean medium, there is also a blocking problem, that is, the impurities in the pipeline are brought into the control valve by the medium, causing blockage. This is a common fault, so the valve should be considered. anti-blocking performance. Generally, the control valve of the angular stroke type has much better anti-blocking performance than the control valve of the linear stroke type.

(3): Whether the pneumatic steam regulating valve is corrosion resistant? It includes erosion resistance, cavitation and corrosion. It mainly involves the selection of materials and the service life of the valve, and at the same time, it involves economic issues. The essence of this problem should be that the selected valve has good corrosion resistance and reasonable price. The angle-shaped high-pressure valve with better anti-cavitation effect and simple structure can be selected, and other high-pressure valves with complex structure and high price can not be selected.
(4): Whether the pneumatic steam regulating valve can withstand pressure and temperature This involves the selection of the nominal pressure and working temperature of the control. In terms of pressure resistance, it is not difficult if the pressure is only high, mainly because the pressure difference will cause cavitation; in terms of temperature resistance, it is usually very easy to solve the problem below 450 °C, and it is not difficult at 450 to 600 °C, but when it is above 600 °C, The contradiction is prominent; when the temperature is 120 ℃, it is usually not advisable to use soft sealing material for the cut-off control valve, and the hard-sealed cut-off should be considered.
