16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?
This is our company's products in Pucheng clean energy Co., Ltd. successful use case, if you need case details, you can give me a QQ number, I sent you. In addition, I suggest you add a pneumatic control valve, so that the safest, no map, I can give you. Saved is to look at the project site, if the north, the electromagnetic valve is recommended to use the 1/2 aperture, and a gas control valve or 1/4, it can guarantee the opening speed of the valve, special attention is on the use of the electromagnetic valve chain, this is very important, I will be the general experience specific issues to deal with specific, can not copy blindly, in most cases, this is no problem. And 1/4 also to see traffic, is also 1/4 solenoid valves, flow valve with big caliber is not the same, is not the same, the 1/4 path from the 2mm-12mm range, the CV value is small, about 0.1, with a large amount of 1.2, has big gap, valve opening time is also a great gap, to distinguish between the.
The valve (including the valve, butterfly valve, etc.) are equipped with pneumatic actuators are standard (including restrictor valve positioner of the electromagnetic valve is connected with the installation.) is the international standard NAMUR standards, in the standard of inside electromagnetic valve is G1/4, of course, this is the solenoid valve installation in the NAMUR interface of the driver on the situation, if the solenoid valve is not installed on the drive, but through the trachea installed in a few meters away, it would have to choose a larger size, how to choose? Depends on the switching speed of the valve requirements, such as drive gas consumption is 2L, need to open in 1S, the electromagnetic the valve requires the flow of 120L/min, plus the line loss and acceleration, 500L/min is enough.
DN200 pick 1/4DN350, DN400 corresponding solenoid valve, you can choose 3/8 hose 12mmOther accessories are related to valve path and pressure. If the same series, the valve has no change at all.
