Buy Motorized Rotary Valve YHF Low Pressure Carbon Steel Flange Type Feeder
The YHF Rotary Airlock Valve from VALVEHU is a precision engineered rotary feeder designed to meter and isolate dry bulk materials such as fly ash, cement powder and granules in dust collection, pneumatic conveying and silo discharge systems. Its rugged cast-iron housing contains a machined eight-blade rotor that maintains tight clearances for minimal air leakage and smooth throughput. Capacities span 2 L to 260 L per revolution, delivering discharge rates from 1.1 m³ h to 143.8 m³ h at 24 rpm, while shaft speed can be varied between 3 and 35 rpm using the integral helical gearmotor.
Flanged inlet and outlet ports simplify installation. Face dimensions range from 190 mm to 860 mm and overall lengths reach 1500 mm on the largest unit, allowing easy integration into both compact and high-capacity layouts. Internal contact surfaces tolerate product temperatures up to 80 °C and the external casing withstands 300 °C, making the unit suitable for service beneath bag filters, cyclones or rotary kilns.
Dynamic rotor balancing, grease-lubricated bearings and a fully enclosed drive train yield low vibration and reduced noise. Drive power options run from 0.55 kW on the 2 L model to 7.5 kW on the 260 L size, with hardened gears for long service life. Optional variable-frequency drives, wear-resistant coatings or stainless steel internals can be specified for abrasive or sanitary duties.
Widely applied in environmental protection equipment, metallurgy, power generation, food processing and chemical plants, this rotary feeder ensures stable feed accuracy and positive airlock, cutting conveying losses and downtime.
