Rotary Airlock Valves

SMB's ROTARY AIRLOCK VALVE’s are designed for various applications, feeding material under high pressure / vacuum with perfect provision of air right scals & uniform discharge from the outlet. It is simplex form of Vane Feeder consists of Airlock Valve Housing, Rotor, Geared Motor, Chain, Sprocket, Chain Guard & Mounting Frame complete. The quantity / flow of material could be adjusted by changing the speed of ROTOR / SPROCKETS. The Rotor blades in pocketed shapes are so perfectly designed that, it handles fine pelverise material, the Rotor is not jammed and also the material is not clogged between the fine gap of the impeller body. The material enters the valve housing from the top & as the Rotor Rotates, each pocket discharges when it reaches the bottom opening of the body.

1) Body of close grained cast iron or fabricated from M.S. to provide adequate stregth, rigidity and high grade quality of casting.
2) Rotor of M.S. / S.S. with shaft ends, machined accurately and mounted on anti-fabrication bearings/ NTN FC Bearings of Japan on request.
3) Rotor vane edges machined and fitted with special fibre / SS linings to facilitate close fit between Housing and Rotor which avoids air leakage.
4) Rotor speed could be regulated to give rated output as may be required to suit site requirements.
5) Various designs of Rotary Air Lock Valve to suit any applications / material.
6) Material of Construction: as per requirement.
