英文：

RVD blanking rotary valve

working principle:

The material falls from the upper hopper into the space between the star shaped blades, and then rotates with the blades to the lower part of the rotary valve, where it is discharged from the discharge port by gravity.

Application scope:

Used as a controllable feeding device in pneumatic conveying systems

Widely used in pneumatic conveying systems for powder and granular materials

Can be used as a controllable and metering feeding device

Can be used as a locking and discharging device for negative pressure chambers and tanks

Usage conditions:

Maximum pressure difference of 0.15MPa

Maximum pressure 0.15MPa

Maximum 120 ℃

Material Science:

Valve body: cast 304/cast steel

Rotor: SS304/carbon steel

Optional structures and attachments:

Shaft mounted reducer

Gas collection hopper

Acceleration chamber (for pneumatic conveying)

▲ Increase the design of inlet and outlet ports, high filling efficiency, and thorough discharge

▲ Reasonable rotor clearance, minimal air leakage, high efficiency

▲ Maze blowing seal, no leakage at the shaft end

▲ External bearing, long service life
