ABSTRACT:
An inlet wall mounted valve device for a central vacuum system is disclosed as having back and front plates arranged on either side of a wall to which the valve device is to be mounted. The back plate, composed of flexible metallic material, is adapted to be compressed and pushed through an opening in the wall having a smaller dimension than the width of the back plate so that the back plate will assume its normal relaxed condition behind the wall and extend beyond side edges of the opening. Fastening devices, such as screws, connecting the front plate to the back plate serve to draw each plate toward the other and thereby attach the valve device to the wall.
