Description
Dust lock rotary airlock valve - Dedusting under cyclone or filter
To regulate and dose conveyed material
The dust control rotary airlock valve is suitable for simple and less demanding industrial applications where its main function is that of a lock.
The dust control rotary airlock valve is specifically designed for gravity discharge and filter applications. The universal flanges on both sides of the valve are drilled to PN 10 and suitable for both round and square flanges.
Operating mode
The dust control airlock has a very large inlet and a direct drive, providing ample torque to the rotor, which has 6 replaceable and adjustable polyurethane blades. An optional steel fixed bladed rotor is also available.
The standard drive is a Nord helical geared motor, type SK01-F-71L/4, 0.37 kW, IP 55, isol. F, giving 27 rpm at 50 Hz and 32.4 rpm at 60 Hz. Suitable for 230/400V 50 Hz and 278/480V 60 Hz.
The standard model is suitable for handling bulk materials up to a temperature of 70°C and a maximum pressure differential of 0.5 bar.
The valve is pressure shock resistant up to 10 bar g pressure.
Equipment advantages
- Minimum air leakage
- Barrier to flame
- Polyurethane rotor blades
- Suitable for both round and square counter flanges
- Versions conforming to ATEX 94/9/EC available, specifications up to Group II Category 1D

Rotary valve - Dust collection Palamatic Process
The rotary dust collection airlock valve is used to regulate and measure the conveyed bulk material.
Rotary valve
The rotary airlock valve has a very large inlet for the operation of the rotor with 6 flexible polyurethane blades that are adjustable and interchangeable.

Flow rate from 2.2 to 19.5 litres/rev.
Features
Technical specification
The inlet of the valve is square, therefore accommodating both round and square outlets from the vessel that has to be discharged. The steep angle of the inlet to the rotor reduces the chance of material bridging.
The outlet from the valve is round for discharge into either a round or square connection.
