For sticky/agglomerated materials causing silo discharge issues.

Abrasion-resistant design and full-bore flow to handle powder without clogging.

Yes, we provide triple-offset metal-seated valves for bubble-tight shutoff.

• 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.

We provide complete packages with manual gear operators, pneumatic actuators (for quick on/off), or electric actuators (for precise control).

Key considerations include: material abrasiveness, pressure requirements, connection type needed, and desired operation (manual/automated). Contact us for specific recommendations.

Yes. We specialize in engineering solutions for unique pressure, temperature, material, or dimension requirements.

Our products are designed and tested to meet relevant ISO, ANSI, and other industry standards, with certifications available upon request.

The choice depends on your application: use a cement silo safety valve for gravity-fed concrete silos, or a bulk tank pressure relief valve for high-capacity storage. We also offer specialized powder tank safety valves for smaller containers.

Clean air nozzles; check air pressure regularly to prevent clogs.

Yes. We offer the pneumatic conveying safety valve for high-velocity transport lines and the air pressure relief valve for compressor units. These ensure reliable set-point activation across your entire plant air system.

Our pressure safety valves for concrete mixing silos feature high compatibility and a “fit-and-forget” design. This simplified installation process reduces equipment adaptation costs and significantly lowers the frequency of routine maintenance.

AKMK provides both flanged and threaded pressure relief valves. For extreme conditions, you can select a weatherproof design or a metal to metal seal safety valve, offering superior durability against abrasive powders.

Iris valves are perfect for free-flowing powders and granular materials. They are particularly effective as an iris valve for pharmaceutical or food-grade powders where gentle handling and hygiene are critical.

Material selection depends on the application. Nylon and polyester are great for general bulk unloading, while silicone and PTFE are preferred for high-temperature or food-safe applications requiring FDA compliance.

Yes. Our AD and IR Single Diaphragm iris valves are specifically designed for unloading bulk material bags. They provide a secure, concentric grip on the bag neck to control flow and minimize dust.

No, iris valves are primarily designed for gravity flow and low-pressure applications. They excel at regulating the flow of material from silos, hoppers, or bags rather than acting as a high-pressure seal.

Regularly inspect the diaphragm for wear or tears caused by abrasive materials. Because we use high-quality materials, our diaphragms are easy to replace, ensuring your iris diaphragm valve continues to operate with precision.

Consider material type, temperature, and dust/moisture levels.

Common ones are loading/unloading equipment, seals, level monitors, cleaning tools, etc., adapting to different silo needs.

It is necessary to consider the silo’s stored materials, capacity and usage scenarios, and prioritize highly adaptable equipment.

Determined by usage frequency; generally inspected every 3-6 months, with wearing parts like seals replaced promptly.

They may lead to material leakage, reduced storage efficiency, and even pose risks to silo structural safety.

Bearings, seals, drive units, and trough liners are typical.

They reduce wear on the trough from abrasive materials.

Replace when there’s excessive noise, heat, or vibration.

Regularly check/replace gaskets; avoid abrasive powder buildup.

Controls powder/granule flow in bulk handling systems (e.g., silos).

Offers fast operation, tight sealing, and easy cleaning for powders.

Disc, valve body, actuator, and sealing gasket (anti-powder-leak).

Regularly check/replace gaskets; avoid abrasive powder buildup.

Help flow of bulk materials from silos using air pressure.
