FREE-VALVE pneumatic operated dome valves is an shut-off valve with in pneumatic conveying environment where abrasive material are passing. Our dome valve features a spherical dome-shaped valve disc,during the opening and closing operation of the dome valve, a controlled clearance is maintained between the valve disc and the rubber sealing ring. Under normal pressure in the sealing chamber, the rubber sealing ring has no contact with the dome, allowing the valve disc and the rubber sealing ring to move in a non contact mode. The valve achieves a sealing effect after pressurization. This design is intended to eliminate friction and reduce wear between the valve disc and the rubber sealing ring.
FREE-VALVE pneumatic operated dome valves is rapidly opening/closing shut-off valve for material conveying. It adopts an advanced air-sealed structure. During valve operation, there is no contact between the hemispherical valve disc and the inflatable rubber seat. It can seal powdery materials and is specially designed for pneumatic conveying systems. It can also serve as an independent shut-off valve for bulk materials. This valve is widely used in industries such as electric power, metallurgy, chemical engineering, and food processing, serving as a shut-off valve for the conveying of powder and granular materials including fly ash and limestone.
