We are engaged in manufacturing and exporting Ash Vessel System, which operates on the principle of Dense Phase Pneumatic Conveying at a low velocity moving through the conveying pipe in separate batches or plugs. The Ash Vessel consists of one-piece body with a top inlet aperture and horizontal inlet and outlet aperture for conveying material. Mounted on the top inlet is a specially designed OSM Engineering Dome Valve, which has a controlled air supply for conveying the material. The Dome Valve is a pressure tight valve. It comprises of a cast iron body, a movable part spherical dome, support shafts and bearing, and integral inflatable rubber seal, a pneumatic cylinder actuator and an air limit switch to operate the inflatable seal.
