The Chantland 4199 Gravity Porta-Valve is a portable, fully-mechanical, gravity bagger designed to fill valve type bags with high density free flowing products such as steel shot and similar materials. The 4199 Gravity Porta-Valve requires no external power and can fill your valve-type bags with high-density free-flowing products at speeds up to (10) 50 lb. bpm with accuracies up to +/- ½ %, depending on product flow and the consistency of bulk density.1 The valve bag is installed on the fill spout, and rests in the bag chair mechanism. When the clamshell gate opens, product gravity flows into the bag. When the bag has reached the designated weight, the clamshell gate closes, and the bag can be removed.
