The mechanical device of the Burkerthttps://heiautomation.com/product/ electromagnetic valve in Germany is a structure where holes are made at different positions in the sealed cavity. In the middle of the cavity, there is a valve, and on both sides, there are two electromagnets. This design enables the valve body to be attracted when the magnetic coil on one side is energized. The position of the hydraulic oil being discharged into the hole is achieved through the movement of the valve body, and then the oil pressure is used to push the piston of the oil cylinder. Thus, the mechanical movementhttps://www.youtube.com/@%E6%9B%BE%E6%85%A7%E5%A9%B7-z6j/shorts is controlled by controlling the current of the electromagnets. Therefore, when using this electromagnetic valve device in daily life, what precautions should be taken?
1、safety：Avoid corrosivehttps://www.facebook.com/profile.php?id=100087291657130 media: It is advisable to use plastic king solenoid valves and all stainless steel; for highly corrosive media, isolation diaphragm type should be selected. For example, CD-F.Z3CF. For neutral media, copper alloy can also be used as the valve body material; otherwise, rust particles often fall off in the valve body, especially in non-frequently operated situations. For ammoniahttps://heiautomation.com/about/ valves, copper materials cannot be used.
2、applicability：Medium form. Different https://heiautomation.com/types of solenoid valves are selected for liquid or mixed states. For example, ZQDF is used for air, ZQDF-Y for liquid, and ZQDF-2 (or -3) for steam. Otherwise, it may cause incorrect operation. The product specifications vary depending on the medium temperature. Otherwise, the coil may burn out, the sealing parts may age, and the service life may be severely affected.
The viscosity of the medium is usually below 50 cSt. If it exceeds this value, for diameters larger than 15mm, use the ZDF series multi-functional solenoid valve. For diameters smaller than 15mm, use the high-viscosity solenoid valve. When the cleanliness of the medium is not high, a backflush filter valve should be installed before the solenoid valve. When the pressure is low, a direct-acting diaphragm solenoid valve such as CD-P can be used as an example. The medium https://heiautomation.com/product/temperature should be within the allowable range of the solenoid valve.
- Pipeline parameters. Based on the requirements ofhttps://heiautomation.com/about/ medium flow direction and the connection method of the pipeline, select the valve ports and models. For example, if a valve is used to switch from one pipeline to two pipelines, a small diameter valve such as CA5 and Z3F should be selected; for medium or large diameter valves, choose ZDF-Z1/2. Another example is for controlling the confluence of two pipelines, select ZDF-Z2/1, etc.
- Environmental conditions. The maximum and minimum temperatures of the environment should be within the allowable range. In environments with high relative humidity and where there are dripping rain, choose waterproof solenoid valves. In environments with frequent vibration, jolting and impact, choose special types, such as marine solenoid valves.
3、reliability：Working life: To ensure quality, one shouldhttps://heiautomation.com/about/ choose well-known brand products from reputable manufacturers.
Working mode: There are three types: long-term working mode, repeated short-term working mode, and short-term working mode.
Working frequency: When the action frequency is high, the structure should preferably choose direct-acting solenoid valves, and the power supply should preferably be AC.
Action reliability. Strictly speaking, this test has not yet been officially included in the professional standards of electromagnetic valves in our country. To ensure quality, one should choose well-known brand products from reputable manufacturers.
