Controlled discharge
Rotary valve and airlock duty
For hopper, silo, drying-line and dust-collection discharge where controlled flow and a consistent air seal matter.
TGF · ZGF · ZGC · BZ family
View suitable familiesGrain
Metering and airlock discharge under grain hoppers, silos and drying lines, with rotary valve and screw conveyor combinations sized to the material and layout.
Food
Cleanable stainless steel rotary valves and conveyors for food-adjacent bulk material lines.
Feed
Rotary valve and screw conveyor combinations for feed mill discharge, transfer and dust-collection points.
Chemical
Rotary valves and crushing valves configured for chemical powder handling, including finer-powder and reinforced variants.
Petrochemical
Reinforced and multi-outlet rotary valve configurations for petrochemical process material discharge.
Pharmaceutical
Cleanable stainless steel rotary valve configurations for pharmaceutical material transfer.
Drying
Rotary valves specified for the thermal conditions typical of drying-line discharge points.
Environmental Protection
Rotary valves and screw conveyors for environmental protection and treatment process lines.
Dust Collection
Rotary valves positioned under cyclones and dust-collection hoppers, prioritizing a consistent air seal.
New Energy
Rotary valve configurations referenced for new-energy material lines, including lithium battery material handling, with a titanium-alloy variant available.
Selection guide
Start with the operating conditions
A useful recommendation starts with the duty point, not a model number. Share the following information so the product family and configuration can be narrowed efficiently.

Material
Bulk material type, particle size and abrasiveness
- 3
Capacity
Required throughput and duty cycle
- 4
Pressure
Operating pressure and air-seal requirement
- 5
