First, the safety: 1, corrosive media: the choice of plastic valve and stainless steel king; for the corrosive medium must use isolation diaphragm. 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, the nominal pressure solenoid valve should exceed the maximum working pressure in the tube. Second, the applicability: 1. Dielectric characteristics 1.1 gas, liquid or mixed state were selected different types of solenoid valve. 1.2 different medium temperature product specifications, or the coil will burn, seal aging, seriously affect the life of life. 1.3 Medium viscosity, usually below 50cSt. If more than this value, diameter greater than 15mm with multi-function solenoid valve for special order. Path less than 15mm set high viscosity solenoid valve. 1.4 medium cleanliness should not be equipped with a recoil filter valve in front of the solenoid valve, the pressure is low fashion optional direct acting diaphragm solenoid valve. 1.5 If the medium is oriented, please make a special request. 1.6 medium temperature should be selected within the allowable range of the solenoid valve. 2.Pipeline parameters 2.1 According to the media flow requirements and pipe connections choose the valve port and model. 2.2 According to the flow and the valve Kv value selected nominal diameter, but also optional with the 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. 2.3 working pressure minimum working pressure differential above 0.04Mpa is optional indirect pilot type such as Shun control SK pilot series solenoid valve; minimum working pressure close to zero or less must be used direct or step-by-step direct type such as Shun control SK Direct motion series solenoid valve. 3. Environmental conditions 3.1 The maximum and minimum temperature of the environment should be selected within the allowable range, if there is any need for special order made over. 3.2 Ambient high relative humidity and rain drops and other occasions, the election should be waterproof solenoid valve 3.3 frequent vibrations in the environment, bumps and shocks and other occasions should choose a special breed, such as marine electromagnetic valve. 3.4 In a corrosive or explosive environment should give priority to use according to safety requirements corrosion resistance 3.5 If the environmental space is limited, please use multi-function solenoid valve, because it eliminates the need for bypass and three manual valves and easy online maintenance . 4. Power Condition 4. 1 According to the type of power supply, were selected AC and DC solenoid valve. In general AC power access convenience. 4.2 voltage specifications exhausted preferred AC220V.DC24V. 4.3 Power supply voltage fluctuations are usually used in the exchange of +% 10% .- 15%, DC allows ±% 10 or so, if ultra poor, to take measures to stabilize the voltage or make special order requirements. 4.4 should be selected according to the power capacity of the rated current and power consumption. 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 5.1 ordinary solenoid valve only open and close two positions, the control accuracy requirements and parameters require stable multi-bit solenoid valve. 5.2 Action time: refers to the electrical signal is turned on or off to the main valve action completed time. 5.3 The amount of leakage Third, the reliability: 1, working life, this item is not included in the factory test items, are type test items. 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. Conventional products are long-term work system, that 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 exchange preferred. 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. Fourth, economic: it is one of the criteria used, but must be safe, applicable and reliable based on the 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. Installation Notes are as follows: 1, the installation should pay attention to the arrow on the valve body should be consistent with the media flow. Do not install in places with direct dripping or splashing water. Solenoid valve should be installed vertically up. 2, the solenoid valve should ensure that the supply voltage of 15% -10% of the rated voltage fluctuations within the normal work. 3, solenoid valve installed, the pipeline may not have reverse pressure. And need to power several times to make it suitable for temperature before formally put into use. 4, solenoid valve installed before the pipeline should be thoroughly cleaned. Access to the media should be free of impurities. Pre-filter valve. 5, when the solenoid valve failure or cleaning, in order to ensure the continued operation of the system, the bypass device should be installed.
