Motorized Double-Deck Air-Lock Ash Valve
HSX Motorized Double-Deck Air-Lock Ash Valves feature gear-motor driven cam and linkage mechanisms that forcibly open and close dual upper and lower sealing flaps in strict alternating sequence. Delivering guaranteed positive discharge and zero blowback under high vacuum and sticky ash conditions.

Forced Positive Mechanical Interlocking
Never sticks even with moist, adhesive, or cohesive fly ash.
Positive Cam-Driven Flap Actuation
Mechanically forces flaps to open and close, eliminating sticking caused by wet or compacted ash buildup.
100% Interlocked Sealing Guarantee
Precision eccentric linkage ensures the upper flap is fully sealed before the lower flap begins opening.
Heavy Slag & Foreign Object Relief
Spring-cushioned flap arms absorb foreign clinker lumps without damaging the drive gears.
High Operating Temperature Rating
Heavy cast steel casing with external water cooling jackets capable of handling flue ash up to +450°C.
Proven in Severe Plant Environments
Delivering high thrust and zero-drift actuation across critical heavy industrial facilities.
Electrostatic Precipitators (ESP)
Primary field hopper ash discharge under severe negative pressure.
Waste-to-Energy Incinerators
Toxic fly ash and heavy bottom boiler ash airlock transfer.
Sintering Machine Windboxes
Sinter dust hopper continuous mechanical discharge.
Coal Gasification Syngas Units
High-pressure gasifier slag discharge lock hoppers.
