The GL rotary valves are specially designed for gravity feeding and pneumatic conveying of granular products. The configuration of the body and rotor has been developed specifically to minimize degradation whilst retaining the best possible pocket filling efficiency. The special inlet construction minimizes the chopping of product. The built-in inlet sheer protector ensures optimal rotor pocket fill. The GL is available in 3 different body configurations: all stainless steel, stainless steel body with aluminum end covers and all-aluminum. The full end disc-rotor is made of 316 stainless steel. The GL valves come in 5 sizes, covering a capacity range from approximately 5 to 79 liters per revolution at 100% filling.
