Compressed Air Inlet
Compressed Air Outlet
Power Inlet
The solenoid enclosure has 1 solenoid for each of the pulse valves to be operated. Each solenoid acts like an electrical switch for compressed air. The solenoid is closed when it does not have power applied to it, meaning that no compressed air is allowed to pass though until power is applied to the electrical coil of the solenoid. As long as the solenoid stays closed, the system remains pressurized which keeps each pulse valve closed. When power is applied to the coil of the solenoid, a small amount of compressed air is allowed to pass through. This small amount of air is all that is needed for the pulse valve to open and allow a larger amount of compressed air to fire down into the cartridge filter. As long as the solenoid stays on allowing air to escape, the pulse valve will continue to fire air into the cartridge filter.
