RVG/H series high-pressure drop-feed granular rotary valve

This valve can be used as a feeding device in low-speed pneumatic conveying systems and can operate under high pressure (working pressure up to 0.35 MPa) for granular materials.

Working principle:

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

Scope of application:

Used as a controllable feeding device in pneumatic conveying systems

Widely used in pneumatic conveying systems for granular materials

It can be used as a controllable and metered feeding device

It can be used as a gas-locking and discharging device for negative pressure bins and tanks

Service conditions:

**Pressure difference: 0.15 MPa

**Pressure: 0.15MPa

**250℃

Material Science:

Valve body: Cast 304/cast steel

Rotor: SS304/carbon steel

Optional structures and accessories:

Axle-mounted reducer

Manifold

Acceleration chamber (for pneumatic conveying)

characteristic

▲Enhanced inlet and outlet design, high filling efficiency, and thorough discharge

▲The specially designed anti-shearing structure of granules ensures consistent quality of raw materials

▲Reasonable rotor clearance results in less air leakage and high efficiency

▲Type B enclosed rotor, with no material leakage at the shaft end

▲External bearing design ensures long service life
