Description
ATEX certification Palamatic Process

Blow-through rotary airlock valve - Dosing of powder for feeding pneumatic convey systems

15 models: flow rate from 5 to 38 litres/rev.
Cast iron, 304, 316L stainless construction

These rotary airlock valves are designed for extraction applications under devices (supported or not), gravity flow or feeding in pneumatic conveying (depression or pressure).

The rotary airlock valves are designed for feeding and controlled discharge of powdered or granular in silos, hoppers, pneumatic conveying systems, bag filters, cyclones in powder handling processes.

The passage of the conveying air through the airlock ensures that the rotor is cleaned by removing the adhered particles from the walls.

Features

Technical specification

Two compartments are filled with product through the spout at the top. After less than a half turn, the rotor discharges the product by gravity into the current generated by the compressed air that passes through the lower part of the rotary airlock valve.
The material is thus transferred. It is connected by flanges to the pneumatic piping at the two ends. The in-line connection of the rotary valve on the pneumatic piping ensures the speed setting of the bulk material. A degassing line may be connected to the valve body to balance the volumes and ensure optimum filling.
