Hefeng Technology's manual powder discharge butterfly valve allows dry powder or small particle materials to fall by gravity, filling the star shaped blade spaces on the top and sides. The blade rotor is driven by a low-speed pneumatic motor (adjustable speed) rotating shaft, and the impeller rotates to the lower part to unload the dust by its own weight.

Hefeng Technology continuously and uniformly feeds the next container in a quantitative manner. Effectively solve some drawbacks of using ordinary butterfly valves that cannot control the feeding speed and amount.
