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
