STASTO Automation · Shut-off technology
Knife gate valves that shut off bulk solids reliably.
Pneumatically actuated knife gate valves (double-acting, A1N series) for powders, granulates and bulk solids – where butterfly valves and ball valves reach their limits. Complemented by related automatic shut-off valves from the STASTO range.
Built for solids.
Why knife gate valves from STASTO
Where bulk solids flow, the right gate matters.
Powders, granulates and abrasive solids need a shut-off that opens fully and closes cleanly. The knife gate valve isolates the full bore – STASTO supplies it with the right actuator, from stock.
Full bore
The blade clears the entire passage – ideal for bulk solids that must not jam.
Pneumatically automated
Double-acting A1N pneumatic actuator – fast, powerful switching.
For demanding media
Robust design for abrasive and dusty solids in process and plant engineering.
Complete shut-off range
Plus seat valves, butterfly, pinch and coaxial valves – all from one source.

How it works
Three steps to the right gate valve.
Tell us the nominal size, medium and actuator – we deliver the right knife gate valve.
Clarify the application
Nominal size, medium (powder, granulate, liquid), pressure and orientation define design and actuator.
Choose valve & actuator
