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 minimise degradation whilst retaining the best possible pocket filling efficiency. The special inlet construction minimizes 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 alumium end covers and all aluminium. 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.
