Filter Bag Solenoid Valve

Pulse valve is composed of pilot head, diaphragm and valve aluminum body. The back cavity area of diaphragm is bigger than the front one. The diaphragm is kept at the closed position due to the effect of big pressure.

Product Details

1.Introduction

Pulse valve is composed of pilot head, diaphragm and valve aluminum body. The back cavity area of diaphragm is bigger than the front one. The diaphragm is kept at the closed position due to the effect of big pressure.

Electrical pulse controller send input signals so that the electromagnetic armature attracts the moving bar. Unclose the balancing hole to release the pressure gas in the back cavity of diaphragm quickly; the pressure gas in the front cavity holds up the diaphragm to open the passage and the valve starts cleaning.

The pulse signal disappears and the spring of the armature works immediately to resume the moving bar so as to close the balancing hole. The pressure gas in the back cavity of the diaphragm and the spring work together to close the passage the valve stops cleaning.

The damping hole in the diaphragm functions to damp the airflow when the moving bar of armature holds up for balancing and to transit the air to the back cavity as soon as the balancing hole is shut to close the passage and stop cleaning..
