High-quality electromagnetic pulse valve
It is always believed that the greater the blowing volume of an electromagnetic pulse valve, the better will the deashing effect become. But in fact this is not scientific after analysis. The function of high-quality electromagnetic pulse valve is to generate a good air pulse meeting the blowing requirement for optimum deashing effect. Then how can a high-quality electromagnetic pulse valve be judged？We think a high-quality electromagnetic pulse valve should satisfy three conditions, namely, ① good switching characteristics；② good circulation ③ reliable service life.
Blowing air volume and negotiability of electromagnetic pulse valve
Test environment in the lab：temperature：35℃，air pressure：0.6Mpa，
Purpose：to collect data on three routes and obtain the blowing volume (l/valve·times) and KV value of each model of electromagnetic pulse valve.
Factors affecting the distance between the blowing pipe and the filter-bag opening
In the past sales many customers inquired about the deashing effect after blowing by an electromagnetic pulse valve. In practice，many factors affect the deashing effect of a pulse valve. Here we have found out the cause-effect relationship through tests in line with the distance between the blowing tube and the swage.

Minimum volume of air chamber matched with pulse valve
The air volume and pressure blown by an electromagnetic pulse valve are major factors affecting the deashing effect of a pulse bag duster filter bag while the volume of air chamber that matches with an electromagnetic pulse valve and pressure of the air chamber in blowing also play a decisive role in the blowing volume of an electromagnetic pulse valve. To guarantee the deashing effect of the filter bag，it is very important to provide the air chamber with a given volume and air supply.
Inspection of deashing effect of the filter-bag
The performance of an electromagnetic pulse valve lies in the deashing effect of a filter bag. When a pulse valve blows，the peak value of the rise in the air pressure at the bottom of a filter bag and the rate of peak value rise will reflect the actual deashing effect.
Development of new products
In order to cater to the needs for fast-growing environmental protection industry, research workers of our company have developed electromagnetic pulse valves of 8, 10, 12 and 14 inches through relentless efforts. Tests show their performance indicators have reached advanced world level and can replace imports. Orders are welcome.
