A pulse valve in a pulse jet baghouse system needs to fire with force and speed in order for the system to run as efficiently as possible. With a pulse valve, the air in the system is pressurized and contains a solenoid valve that releases the pressurization, which in turn releases the compressed air into the blow pipe.
The pulse valve has a connection to a solenoid which may be located in a solenoid box, or the controller. The solenoid can also be an integral solenoid which means it is located directly on the pulse valve. It is likely that the pulse jet baghouse system is more efficient with an integral solenoid because you have a direct and close connection. When the solenoid opens it depressurizes the back side of the pulse valve and you get an immediate reaction.
If the solenoid is located in the control or box solenoid, which may be connected through copper or plastic tubing, this creates a problem when the solenoid opens especially if your solenoid is a long distance away. All of the pressurized air needs to be released so you do not have a solid pulse in your system. Instead of the pulse opening and closing quickly, you get the opposite effect of a pulse building up and then slowly dissipating.
The solution for this problem is to place the solenoid as close as possible to the pulse valve for your system to run in the most productive and efficient manner.
