A: Applicability The fluid in the pipeline must be consistent with the medium calibrated in the selected solenoid valve series models. Fluid temperature must be less than the selected solenoid valve calibration temperature. Solenoid valve to allow liquid viscosity generally below 20CST, greater than 20CST should be noted. Working pressure, the maximum pressure pipe when less than 0.04MPa should be used, such as ZS, 2W, ZQDF, ZCM series, such as direct acting and step-by-step; minimum working pressure greater than 0.04MPa can be used when the pilot Differential) solenoid valve; maximum working pressure difference should be less than the maximum calibration solenoid valve pressure; general solenoid valve are one-way work, so pay attention to whether there is anti-pressure difference, if installed check valve. The fluid cleanliness is not high should be installed in front of the solenoid valve filter, the general requirements of the solenoid valve cleanliness is better. Pay attention to the flow aperture and take over the caliber; solenoid valve generally only two switches control; conditions permit installation of the bypass pipe, easy maintenance; water hammer phenomenon to be customized when the solenoid valve opening and closing time adjustment. Note that the ambient temperature on the solenoid valve power supply current and power consumption should be selected according to the output capacity, the power supply voltage is generally allowed ± 10%, we must pay attention to AC starting VA value is higher. Second, the reliability of the solenoid valve is divided into two types of normally closed and normally open; generally use the normally closed type, power open, power off; but a very long time to open a very short time to open the normally open type. Life test, the factory generally belongs to the type test project, to be exact, our country does not have the professional standard of the solenoid valve, so carefully choose the solenoid valve manufacturer. Action time is very short When the frequency is higher, select the direct-acting type, large-diameter selection of fast series. Third, the general safety of the solenoid valve is not waterproof, please do not allow the waterproof conditions, the factory can be customized. The highest nominal pressure solenoid valve nominal pressure must exceed the maximum pressure within the pipeline, otherwise the service life will be shortened or other unexpected situations. A corrosive liquid should be used in all stainless steel, corrosive fluids should use the plastic king (SLF) solenoid valve. Explosive environment must choose the appropriate explosion-proof products. Fourth, the economy There are many solenoid valve can be universal, but to meet the above three points should be based on the selection of the most economical products.
