What Pneumatic Conveying Needs from a Valve
Pneumatic conveying moves dry bulk solids through pipelines using air flow - either dilute phase (high velocity, low pressure) or dense phase (low velocity, high pressure). Valves in these lines face three enemies: abrasion from the moving product, clogging where material can collect, and sealing failure. That is why our conveying-line valves are abrasion-resistant, full-bore, fast-acting and reliable over hundreds of thousands of cycles.
Our Valves for Pneumatic Conveying Lines
Dense phase or dilute phase, the valve is where a conveying line either keeps running or stops. Every XNFM valve in this family is built for that duty - full-bore so slugs pass without bridging, abrasion-resistant so the wear part is cheap to swap, and leak-tight so dust stays in the pipe. DN40 to DN600, manual or automatic, with replaceable sleeves and seats you can change in minutes.
Dense Phase vs Dilute Phase - Selection Guide
Pinch Valves (VF / VMP / PVE)
Media never touches metal - sleeve only, zero clogging. Ideal for shut-off and flow control on conveying lines.
Diverter Valves (VAB / KFQ / KFZ)
Leak-tight, wear-resistant flow switching from one line to another. Full-bore options available.
Iris Valves (AD / IR / KD)
Smooth full-bore-to-closed motion for dosing and metering at line end. No jamming.
