Rotary valve (airlock)

 Brief  introduction :

 Bulk Tech Rotary airlock valves (which can also be called airlock) are used in a wide range of applications , where there is a need to minimize system air losses while transferring solid bulk material between chambers with different pressure level and dose and feed solid bulk products within the processes in the pharmaceutical, chemical and food industry

Where do we use it ?

1,   For   industries   :    biofuels  / biomass energy / wood chips / Sawing wood ash dust / sugar /  stone and pellet / grains / PET /PVC   .

2,   For application   :    dust collection /  pneumatic convey /  bulk material covey /  dose and feed system /  gravity discharge / hopper and bin / silo and other process .   

A letter to you

Rotary valves on Alibaba is mixed up by both good quality and bad quality . Many small workshop (or amateur doing rotary valve for part-time job) owns one or two rooms and five workers starts to produce rotary valve . To save cost, they buy cheap bearing and motor for rotary valve. They have very good advertisement and say they are good quality and big manufacturer . Some customers told us “they are  good quality and cheap” which embarrassed us . When those customers bought rotary valve and broken in two months. They never get paid and can’t find suppliers anymore .

Lots of trade company don’t respect quality at all and never take responsibility for customers. They searched for low price with bad quality to attract customers. That cost huge lose for final users and engineering company lost their own customers too .And then some customers never trust madeinchina anymore.

We are the export department from our own factory. We offer our quality rotary valve with conscience. If you want us to proof, we can show you to our factory and even offer you rotary valve from small workshop , you can compare.

The common trouble of rotary valve on market  :

Probem :      Scratches , when rotary valve running, rotary valve may have 

big noise  and the rotary  valve will be broken in any time , whole project has to stop 

,which  make the project loses lots of money per day. 

Cause Reason :               Cheap raw material 

Bulk Tech Solution :    Bulk Tech rotary valve uses quality of raw material , 30% 

more cost on raw material . Like QT600 / SS304/ SS316 /Mn steel /  Carbon steel 

from big formal company.

Problem : Rotary valve stops runing . Project stops .

Cause Reason :  Cheap  bad bearings broken fast . Then rotary valve stops running !  

Bulk Tech solution :Bulk Tech rotary valve uses different Bearings . Japanese C&U bearing / SKF  /FAG.We choose the best for you. Our bearings will not be broken for 5 years. 

Problem :   Rotary valve stucks 

Cause Reason : Wrong seals and wrong rotor choice 

Bulk Tech solution :  Bulk Tech rotary valve knows seal well ,we have packing seal, rubber

,Teflon,mental seal and air purge seals. Our rotary valve can prevent from stucks

Problem : rotary valve distort and stucks

Cause Reason : Small factory try to save money or don't know the process of aging treatment 

Bulk Tech solution : Bulk Tech has strict process on producing rotary valve . We have long 

time aging treatment and Precision casting ensure rotary valve strong and stable

Examples of project installed with bulk tech rotary valve  :

1 Project ICIBA

2 Project COFCO

3 Project WDL
