I. Security: do not pay attention to safety that will produce a disaster! 1. Corrosive media: the choice of plastic valve solenoid valve and stainless steel; for the strong corrosion of the media must use isolation diaphragm. Example CD-F. Z3CF. Neutral medium, copper alloy should also be used as the valve material of the solenoid valve, otherwise, the valve shell often rust off, especially when the action is not frequent. Ammonia valves can not use copper. 2. Explosive environment: you must choose the appropriate level of explosion-proof products, open-air installation or dust should be more occasions use waterproof, dustproof varieties. 3. Solenoid valve nominal pressure should exceed the maximum working pressure tube. Applicability: Does not apply to spend money to buy things, but also add trouble! 1.Material Characteristics The gas, liquid or mixed state were selected different types of solenoid valve, such as ZQDF for air, ZQDF-Y for liquid, ZQDF-2 (or -3) for steam, otherwise easy to cause malfunction. ZDF series of multi-function solenoid valve is available in the gas. Liquid. The best time to state the media state, the installation users do not have to adjust. Medium temperature different specifications of the product, or the coil will burn, seal aging, seriously affect the life of the life. Medium viscosity, usually below 50cSt. If more than this value, diameter greater than 15mm with ZDF series of multi-function solenoid valve for special order. Path less than 15mm set high viscosity solenoid valve. Media cleanliness should be equipped with a recoil filter valve in front of the solenoid valve, the pressure is low fashion can choose direct acting diaphragm solenoid valve for example CD-P. If the medium is directional and does not allow backflow ZDF-N and ZQDF-N need to be used in both directions, please make a special request. Medium temperature should be selected within the allowable range of the solenoid valve. 2.Pipeline parameters According to the media flow requirements and pipeline connection options valve port and model. For example, the small diameter selection CA5 and Z3F for one pipe to two pipes, ZDF-Z1 / 2 for medium or large diameters. Another example is the control of the convergence of two pipelines, please choose ZDF-Z2 / 1. According to the flow and the value of the valve Kv nominal selected diameter, but also choose the same pipe diameter. Please note that some manufacturers are not marked with Kv value, often the size of the valve hole is smaller than the interface diameter, must not be greedy price low and misleading. Working pressure differential minimum working pressure above 0.04Mpa is optional indirect pilot; minimum working pressure close to zero or less must be used direct or step-by-step direct type. 3. Environmental conditions The maximum and minimum temperature of the environment should be selected within the allowable range, if there is a special order to be made out of tolerance. Relative humidity in the environment is high and there is rain drops and other occasions, should choose waterproof electromagnetic valve environment often have occasions such as vibration, bump and impact should choose special varieties, such as marine electromagnetic valve. Use in corrosive or explosive environment should be selected according to safety requirements Resistant to corrosion Environment space is limited, please use the multi-function solenoid valve, because it eliminates the bypass and three manual valves and easy on-line maintenance. 4. Power Conditions According to the type of power supply, were selected AC and DC solenoid valve. In general AC power access convenience. Exhaustion of voltage specifications preferred AC220V.DC24V. Power supply voltage fluctuations usually use +% 10%.-15% AC, DC allows ±% 10 or so, if over-tolerance, to take measures to stabilize the voltage or make special order requirements. Select the rated current and power consumption based on the power capacity. Should pay attention to AC starting VA value is higher, in the lack of capacity should be preferred indirect induction solenoid valve. 5. Control accuracy Ordinary solenoid valve only open and close two positions, high precision control parameters and parameters require stable multi-position solenoid valve; Z3CF three normally open solenoid valve, with micro-Kai, fully open and closed three Flow; ZDF-Z1 / 1 combination of multi-function solenoid valve with full open, wide open, small open, full open four flow. Action time: refers to the electrical signal is turned on or off to the completion of the main valve action time, only the company's patented multi-function solenoid valve can be opened and closed separately adjusted, not only to meet the control accuracy requirements, but also to prevent water hammer damage. Leakage samples given the amount of leakage for the commonly used economic level, if too high, please make a special order. Third, the reliability: unreliable will damage the entire system! 1, working life, this is not included in the factory test project, a type test project. In order to ensure the quality of regular manufacturers should be selected brand-name products. 2, work standard: long-term work system, repeated short-term work system and short-term work system three. The Company's conventional products are long-term working system, that is, the coil allows long-term power work. For a long time to open the valve only a short time off, it should be used normally open solenoid valve. Used in short-time working system and the volume is very large, special orders can be made to reduce power consumption. 3, the working frequency: high frequency of operation, the structure should be preferred direct-acting solenoid valve, the power to listen to the preferred exchange. 4, the reliability of the operation Strictly speaking, this test has not yet been officially included in the professional standards of our solenoid valve, to ensure the quality of the regular manufacturers should choose the brand-name products. In some occasions, the number of actions is not much, but the reliability requirements are very high, such as fire protection, emergency protection, must not be taken lightly. Particularly important, you should also take two double insurance. Economies: Ineconomy is one of the criteria used to waste capital, energy and even life, but it must be based on a safe, applicable and reliable economy. Economy is not only the selling price of the product, but also the priority given to its function and quality as well as the cost of installing maintenance and other accessories. More importantly, the cost of a solenoid valve in the entire automatic control system in the entire automatic control system and the production line is minimal, if you seek a cheap and missed the early damage caused by the group is huge. In short, economy refers not only to the product price, but to the product's cost performance to price ratio.
