Nuoguan norgren solenoid valve calibration temperature

applicability
The fluid in the line must match the medium calibrated in the optional norgren solenoid valve series. The temperature of the fluid must be less than the calibration temperature of the solenoid valve selected. Norgren solenoid valves allow liquids to be generally below 20 CST and should be noted above 20 CST. Working pressure difference, the maximum pressure difference of the pipeline should be less than 0.04MPa, such as ZS, 2W, ZQDF, ZCM series and other direct-acting and step-by-step direct-acting type; when the working pressure difference is greater than 0.04MPa, the pilot type can be used. Differential) Solenoid valve; the highest working pressure difference should be less than the large calibration pressure of the solenoid valve; the general solenoid valve is one-way work, so pay attention to whether there is a back pressure difference, if there is a check valve installed.
When the fluid cleanliness is not high, the filter should be installed in front of the solenoid valve. Generally, the solenoid valve requires good cleanliness of the medium.
Pay attention to the flow aperture and the diameter of the nozzle; the solenoid valve is generally only controlled by the two-position switch; if necessary, please install the bypass tube for easy maintenance; when there is water hammer, customize the opening and closing time of the solenoid valve. Pay attention to the influence of ambient temperature on the solenoid valve. The power supply current and power consumption should be selected according to the output capacity. The power supply voltage is generally allowed to be ±10%. It must be noted that the VA value is higher when the AC starts.

Second, reliability
The solenoid valve is divided into two types: normally closed and normally open; generally, the normally closed type is used, the power is turned on, and the power is turned off; but when the opening time is long, the normally open type is selected when the closing time is short. Life test, the factory is generally a type test project, to be exact, there is no professional standard for solenoid valves in China, so the choice of solenoid valve manufacturers is cautious. When the action time is short and the frequency is high, the direct motion type is generally selected, and the large diameter is selected as the fast series.

Third, security
Generally, the solenoid valve is not waterproof. When the conditions are not allowed, please choose waterproof type, the factory can be customized. The highest nominal pressure of the solenoid valve must exceed the maximum pressure in the pipeline, otherwise the service life will be shortened or other accidents will occur. Corrosive liquids should be selected from all stainless steel type, and strong corrosive fluids should be selected from plastic king (SLF) solenoid valves. Explosive environments must use the corresponding explosion-proof products.

Fourth, economic
There are many solenoid valves that can be used universally, but the most economical products should be selected on the basis of meeting the above three points.
