As a leading Chinese manufacturer, AKMK designs robust industrial butterfly valves for the world's most demanding environments. Our valves deliver reliable shut-off, control, and isolation specifically for abrasive bulk solids, powders, and harsh media—making them the proven choice for cement plants, concrete batching, and pneumatic conveying systems.
Engineered to conquer challenges like fly ash and cement, our valves integrate key durability features: abrasion-resistant components combat wear, dust-tight seals prevent loss and contamination, and full-bore designs ensure smooth flow without clogging. From silo discharge to critical process points, they guarantee efficiency and longevity.
Do you provide custom valves for specific applications?
Yes. We specialize in engineering solutions for unique pressure, temperature, material, or dimension requirements.
Are your valves compliant with international standards?
Our products are designed and tested to meet relevant ISO, ANSI, and other industry standards, with certifications available upon request.
What’s a powder butterfly valve used for?
Controls powder/granule flow in bulk handling systems (e.g., silos).
Why choose it over other powder valves?
Offers fast operation, tight sealing, and easy cleaning for powders.
What key components does it have?
Disc, valve body, actuator, and sealing gasket (anti-powder-leak).
What are the main differences between wafer, lug, and flanged butterfly valves?
Wafer type: Most economical, installed between pipe flanges using through-bolts.
Lug type: Has threaded inserts allowing installation between flanges or at pipe ends without nuts.
Double flanged: Most secure connection, ideal for high-pressure applications or direct mounting to equipment like silo outlets.
What actuator options are available?
We provide complete packages with manual gear operators, pneumatic actuators (for quick on/off), or electric actuators (for precise control).
How do I choose the right valve?
Key considerations include: material abrasiveness, pressure requirements, connection type needed, and desired operation (manual/automated). Contact us for specific recommendations.
