Double Shuttle Valve having a pair of valve plugs slideably mounted within a hollow body.

Driveless double shuttle valve
A double shuttle valve is constructed of two autonomous flaps, pressed down to the feeding section by means of weights installed on a lever. Proper location of weights depends on the type and quantity of the dust. Valve opening adjustment must be set so that the upper valve opens after the upper section is fed with the dust, supplying the dust to the bottom valve, which eventually closes. As subsequent portions of dust are supplied, the bottom valve opens and the dust is removed from the equipment. The use of adjustable weights facilitates adjustment of the valve opening frequency.
Double shuttle valve with a drive
A double shuttle valve is constructed of two levels of flaps, pressed down to the feeding section by means of springs. The flaps are opened and closed by means of a cam installed on a motor-gear. Valve opening adjustment must be set so that the upper valve opens after the upper section is fed with the dust, supplying the dust to the bottom valve, which eventually closes. As the upper valve is closed, the bottom valve opens and the dust is removed from the equipment. The use of a motor-gear facilitates emptying of the system in the equal intervals of time and guarantees 100% tightness of the system .
