VM Series Pneumatic Pinch Valve 13–200 mm for Powder & Granule Conveying
VM013–VM0200 | Aluminum Body | Full-Bore Flow Path | Pneumatic Sleeve Shut-Off
💨 Designed for pneumatic conveying lines handling powders, granules, dust and selected fibrous materials.
The VM series uses compressed air to squeeze the internal flexible sleeve, providing a simple shut-off solution without placing a disc, gate or ball directly in the material passage.

🔍 Why Buyers Choose the VM Series
Full-Bore Material Passage
When the valve is open, the material travels through the flexible sleeve without a conventional disc or gate positioned across the bore.
This is particularly useful in conveying lines where powder or granular material could otherwise collect around internal valve components.
Sleeve-Based Pneumatic Shut-Off
Compressed air acts around the sleeve and squeezes it inward to close the material passage.
The shut-off function therefore comes from the sleeve itself rather than a separate mechanical closure element moving through the conveyed product.
Only the Sleeve Contacts the Conveyed Material
The internal sleeve separates the conveyed medium from the valve housing, simplifying the internal flow path and reducing direct exposure of the body to the material stream.
Service-Focused Design
For maintenance planning, the flexible sleeve is the key service component.
Replacement projects can therefore be matched using the existing VM model, bore size and installation dimensions.

For replacement projects, flange and installation dimensions should be confirmed against the exact VM model before ordering.
💨 Operating Limits Matter
The available compressed-air pressure should not be considered by itself.
For correct sleeve closure, the control pressure must remain higher than the pressure inside the conveying line.
Pipeline pressure:
Pi
Control pressure:
Pc
Closure condition:
Pc = Pi + 2.5 bar
with a maximum control pressure of 6 bar.
This makes pipeline pressure one of the most important pieces of information to provide when requesting a quotation.
🧱 Suitable Conveyed Materials
The VM series can be considered for suitable dry bulk materials such as:
Cement Powder · Mineral Powder · Plastic Pellets · Grain · Feed Ingredients · Chemical Powder · Dust · Fine Granules · Selected Fibrous Materials
Final suitability should be confirmed according to particle characteristics, temperature, sleeve compatibility and actual conveying conditions.
🏭 Where It Is Used
Typical applications include:
Chemical Processing | Plastics | Food & Grain | Cement | Building Materials | Mining | Mineral Processing | Waste Recycling | Pneumatic Conveying Systems
The valve is especially suited to process positions requiring full-bore conveying during operation and pneumatic isolation when the line needs to be closed.
🧩 Replacement & OEM Supply
VM valves can be supplied for:
New conveying systems · Existing valve replacement · Equipment manufacturing · Spare-parts distribution · Project purchasing · OEM / ODM orders
For replacement orders, supplying the existing VM model and installation dimensions can significantly reduce matching errors.
