Rotary Valves / Air-Lock Systems
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 part
coming in direct contact with the product is made of AISI 304/316/MS as
desired by party.
