Flow through rotary airlock valve to handle material that are fragile, abrasive etc

To be used under negative pressure conveying cyclone, flow-through rotary airlock valve adopts detached foundry, of which all components have been precisely processed before assembling. It has exquisite configuration and anti-blocking design, which can solve material stuck problem without dismantling. The hole at the end of bearing is for observing sealing efficiency at any time, and the observation window on the top is for following up the process of discharging. This type of valve offers series connection solution, using single power to drive multi-valves. Ultimately, it can save energy and reduce purchasing cost. 

Main Features:

• Highly economical


• Broad range of application


• Low energy consumption


• Excellent sanitation

 Principle of air lock 

the machine has a casting case and a rotary wheel inside. The materials  are fed from the top inlet and discharged from the bottom outlet through the rotating wheel. The main function of this machine is shut off the aspiration air flow with the atmosphere while separating the materials from pneumatic line or aspiration air flow

Features of air lock:

Advanced design and excellent fabrication ensure the air tighten sufficiently while the rotating running  smootly.

with sight glass at the inlet for intuitionic inspection

At most 7 units machine can be connected together to share a gear motor.

Made by stainless steel, high sanitation

Application of air lock:

Normally airlocks are installed underneath the pneumatic cyclones and air jet filters for the discharge of mill stock, filter dust in the food processing industry.

Can also be used as a ration machine for feeding materials such as grain, break stock, semolida, flour and other materials with similar characteristics from pneumatic conveying lines
