Dome valve

Product introduction of QQF dome valve (spherical feed valve)

QQF spherical feed valve (dome valve) is a new type of special valve for ash removal. It is a cast iron shell structure. There is a rotatable Cast Iron Dome with two stainless steel rotating shafts inside. An inflatable dome seal ring is installed in the valve dome. When the valve works, there is no contact between the dome and the inflatable seal ring, and the seal ring is made of special formula rubber. It is the key part of pneumatic conveying system.

When the valve top moves, it has no contact with the sealing ring, so the operation resistance is small and the service life is long;

The pneumatic actuator adopts fully enclosed rotary push rod type straight cylinder drive, with rotary output, reliable performance and large output torque, which can meet the working conditions.

The sealing ring is made of special material, which has a wide range of temperature resistance; the crankshaft is designed, which can fully flow when the valve is opened, and protect the dome sealing surface.
