Rotary airlock - Bulk material and powder handling
Description

Dust lock rotary airlock valve - Dedusting under cyclone or under filtre

ATEX certification Palamatic Process

To regulate and dose the material conveyed
The dust control rotary airlock valve is suitable for simple and low demanding industrial applications, where its main function is that of a lock.

The dust control rotary airlock valve is of a dedicated design for filter applications. The universal flanges on both sides of the valve are drilled to PN 10 and suitable for both round and square counter flanges.

Operating mode

The dust lock airlock has a very large inlet and a direct drive, providing ample torque to drive 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

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 angle of the inlet down to the rotor has been kept as steep as possible, to reduce the chance of bridging.

The outlet from the valve is round, so that you can discharge into either a round or square connection.
