Special Type Rotary Valve Discharge Valve Dust Cast Iron Square Outlet Discharge Valve is easy to disassemble. High-Temperature Resistant Type: Due to the varying temperature rise during material conveying and discharge, which affects the thermal expansion of the body and is detrimental to the bearing and oil seal system, our factory has designed a high-temperature resistant external structure ash discharge valve. It separates the operating parts from the material-contact box section, ensuring the safe operation of bearings and oil seal systems unaffected by temperature fluctuations. This product not only withstands high

temperatures but is also highly effective for conveying and receiving hygroscopic materials and metallic powders. These materials have penetrative properties that can bypass oil seals and directly enter bearings, causing operational failure and mechanical damage. Thanks to its external design, it avoids contact with materials. The high-temperature resistant ash discharge valve can handle material temperatures up to 500°C and uses sprocket connections.

Pressure-Resistant Type: It features a closed rotor and is widely used in suction, pressure, and negative pressure pneumatic conveying systems. It ensures no leakage of airflow pressure within the conveying pipe, enabling safe material transport and collection, hence known as an airlock valve. It not only withstands pressure but also incorporates the functions of standard types.

Star-type ash discharge valves are categorized by their external structure into round and square types. Their advantages include: stable and reliable operation, uniform and accurate discharge, optimized structure, compact size, excellent sealing performance, easy maintenance, energy efficiency, and long service life. They are essential equipment in drying, dust, granule, and solid conveying systems. This valve is installed at the dust discharge outlet of dust collectors and is widely used in feeding and ash discharge systems across industries such as chemical, metallurgy, mining, cement, dust removal, environmental protection, power, and food. Custom non-standard star-type ash discharge valves are available based on customer requirements.
