G.D.Machines  manufactures Rotary Air Locks used for feeding materials under vacuum or pressure while sealing in air and gas. The principle of gravity is used for dropping the material in the container. This is done with the help of a vaned rotor. The rotor consists of 5 vanes and is available in different diameters as per the requirement of the process. The rotary air lock consists of rotor with minimum clearance of 0.5 mm between vane tip and interior of body. This is done to ensure perfect air locking considering the wear and tear of the rotor after use. The rotors are driven with the help of standard motor and gearboxes.

G.D. Rotary Valves are very reliable, controlled feeding from or into silos and hoppers in a very confined space. They are also perfectly tuned to the production process in which they will be used. They have highly filling efficiency due to effective inlet shape and close running clearances with low air leakage. Due to Heavy Duty Ball Bearing provided on both sides of the Rotor, Rotary Valves are able to handle powders. Each and every parts coming in direct contact with the product are made of AISI 304/316/MS as desired by party.
