Pneumatic Slide Gate
Automated, Dust-Tight Flow Control for Bins, Hoppers & Ducts
Pneumatic Slide Gate for Precise, Automated Flow Control
A pneumatic slide gate valve is an air-cylinder-operated gate installed under bins, hoppers, silos or ducts to open, close or divert the flow of bulk material such as paddy, rice, flour or powder. A rectangular slide plate moves between polymer/UHMW guide strips that both seal and self-clean as the plate travels.
Agromach's version is built for rice-mill duty: heavy-gauge carbon or stainless steel body, replaceable wear-resistant seals, and pneumatic cylinder actuation that can be tied into limit switches, solenoid valves and PLC logic for remote or automated operation.
- Air-cylinder actuated gate for fast, repeatable control
- Self-cleaning slide action with replaceable seals
- Works under gravity, pressure, or vacuum conveying lines
- Integrates with solenoid valves, limit switches, and PLC
The Cost of Poor Flow Control at Bin, Hopper & Duct Outlets
Manual gates at discharge points create recurring losses on the mill floor:
- Manual gates are slow and depend on an operator at every point
- Worn or ill-fitting gates leak material, causing loss and dust
- Inconsistent, operator-dependent closing gives uneven batches
- Operators near discharge points face pinch-point safety risks
- Manual gates cycle too slowly for emergency shut-off or batching
Left uncontrolled, these issues compound into lost material, inconsistent output, and avoidable safety incidents.
Agromach's Pneumatic Slide Gate Advantage
Agromach's pneumatic slide gate valve replaces manual gate operation with air-cylinder actuation that opens and closes in a fraction of the time, sealing tightly between cycles.
Rapid, repeatable actuation with a tight-sealing slide blade that stops flow cleanly when closed.
- Rapid opening/closing suited to batching and emergency shut-off
- Low-leakage sealing minimizes material escape and dust
- Consistent, repeatable cycling supports accurate metering
- Remote or PLC-automated operation keeps personnel away from hazards
- Self-cleaning slide action reduces buildup and seal wear
Reliable automated gating keeps flow steady, losses low, and operators safely away from the discharge point.

Pneumatic Slide Gate Price
The pneumatic slide gate price depends on:
- Body/slide-plate material and surface finish
- Gate size and valve type (slide vs. diverter vs. knife gate)
- Cylinder actuation type and accessories
- Seal material and sealing configuration
- Automation level — manual override only vs. full PLC integration
