Select all imports of high-quality brands: electromagnetic pulse valve but the heart of the dust removal equipment, the total price is about 5% of the overall price of the pulse jet dust collector; 1% cost of the air box pulse dust collector, the choice of the highest quality import pulse valve, the total equipment cost than the use of domestic valve has only increased by 1 to 2 percent. Pulse valve to save the cost of equipment and bear the risk of failure of the whole dust removal system is the most worthwhile. 
 Valve manufacturer with a long history: the valve manufacturer must have more than 10 years of production history and operation of successful cases, so as to ensure pulsed solenoid valve products have perfect quality assurance system, the real injection 10 million The annual exemption. 
 Choose the five-year free warranty period: the number of experimental pulse valve action sufficient to show the quality level of the valve, the diaphragm must go through years of natural aging factor test. Valve suppliers must provide free warranty period of the diaphragm and the solenoid coil, generally for five years. 
 Not just connected to the interface size of the aperture size: the pulse valve injection gas pulse valve, often can not determine the cleaning function. Some pulse valve design uses a small diameter of the diaphragm, but only to increase the interface. For example: the application of the valve diaphragm installed in the valve body of the 21/2 interface. So make the injection gas valve caused by inadequate cleaning system is poor. 
 High, medium and low pressure range that applies to pulse valve: the pressure range of the pulse valve requires at least 1 ~ 8Kg/cm2. So, if the filter resistance in the application process is increased over time, by adjusting the air bag pressure to keep the dust collector running resistance, ensure that the filter does not paste bag. 
 Select the quality of the production of unity of the pulse valve: the valve manufacturing, automatic production lines equipped with robots and CNC center, put an end to the production of quality due to human processing is not uniform. In a cleaning system, often due to a valve leak which led to the paralysis of the entire system. 
 Pulse valve to select low-resistance: the internal structure of the pulse valve injection volume, long stroke diaphragm shell structure according to the hydrodynamic design so that the valve resistance is small. Some 3 "interface due to the improper design of the valve, valve injection gas can only reach" 1 "interface valve injection gas. Selection of low resistance, high injection volume of each pulse valve valve cleaning a larger area of ??the filter, significant savings in overall cost of the injection system due to the reduction of the number of valves, the precipitator operation and maintenance costs are reduced accordingly.

 Electromagnetic pulse valve of the five selection methods: 
 An electrical options: voltage specification should be preferred AC220V, DC24 more lunch. 
 Second, based on pipeline parameters to select electromagnetic valve: Path specification (DN) of interfaces 
 1, in accordance with the scene inside diameter of pipe size or flow request to confirm the size of the diameter (DN). 
 2, interface mode,> of DN50 to choose the flange interface, ≤ of DN50 can freely choose according to user needs. 
 Select solenoid valve: material, temperature group, according to the fluid parameters 
 A corrosive fluid: better to use corrosion-resistant solenoid valves and stainless steel; eating superclean Fluid: should use food grade stainless steel solenoid valve. 
 2, high-temperature fluids: using high-temperature electrical information, the solenoid valve and seal the information manufacturing, but also to select a piston constructed type. 
 3, the fluid state: gaseous, liquid or mixed state, especially a diameter greater than DN25 order must identify the open. 
 4, the fluid viscosity: usually 50cSt the following can be arbitrary choice, beyond this value will have to use high viscosity valve. 
 Fourth, to choose according to the length of the continuous working time: normally closed, normally open, or sustainable power 
 1, when the solenoid valve needs to open a long time, and duration of the excess time off should be used in a normally open type. 
 2, I opened a short time or on and off time is running out, then select normally closed type. 
 3, but some conditions for safe maintenance, such as furnaces, kilns, flame monitoring, you can not select normally open, to be elected may be long-term power type. 
 Select solenoid valve: principles and structure types, according to the pressure parameters 
 Pressure: this parameter and the meaning of other general purpose valves are the same, is based on the pipe nominal pressure. 
 Working pressure: If the low pressure is necessary to use direct action or step straight action principle; minimum working pressure is acting the 0.04Mpa more than straight, step-by-step direct-acting, Pilot operated can be selected.
