·Applicable Field： Grain, forage, chemical industry ·Applicable Material：Powders, particulate matter, or crushed material. ·Function：Receiving, discharging materials by pneumatic conveying and ensuring the stability of pressure of air network system ·Performance characteristics：Backplane drive, external and separable bearing, modular sealing, being able to quickly change sealing methods according to the demand ·Patent No.: 201420016643.0/201420016638.1Positive Pressure Conveying Drop-through Rotary Valves are the most basic and common type of rotary valve. Usually they are widely used in the powder and granule positive pressure pneumatic conveying systems. They feed material that falls through the inlet, moves down though the rotating vanes where it drops out the bottom outlet flange via gravity. This design is capable of feeding materials in a vast array of applications. In a pneumatic conveying system, a convey adapter or shoe must be installed below the valve to transfer the product into the conveying line where it is blown or sucked downstream.The drop-through valve is used mainly for relatively free-flowing, non-cohesive materials such as grain, rice, coffee beans, salt, and sugar.

Q1. Are you a manufacturer or a trading company, do you accept OEM ? A1. We are manufacturer and we have been in the rotary airlock valve and diverter valve filed for almost 20 years. We have our own engineer team and up to now we have got several patent of our own. We can customize according to users usage. Q2. What are your advantages  ? A2.Our Airlocks can operate smoothly for 6-8 years with SKF Bearings, The gap between the rotor and the shell reaches the centimillimetre level, and the wind shutoff effect is good. And professional design with our own patents. Since we are manufacturer, we have our own supply chain and quality control system. So we can provide competitive price as well as good quality. Q3. What kind of payment terms and transportation do you accept ? A3. We accept payment through Alibaba, TT, LC etc. Air transportation and sea transportation are available.
