Product Description

Capability and Usages:
RIG****1 Butterfly Valve consists of two half valve bodies which are made by gravity irrigation. The material of the half valve is aluminum alloy and rotary valve plates is made of polymer material providing a good sealing property. The main function is to assist the switching of the feed box, hopper as well as silo that might contain powdery or particle materials. It is suitable for processing all powdery or particle materials. Valves make use of the gravity of material itself to cut off the flow and transfer dry materials pneumatically. It can be installed underneath hopper, feed box, silos, screws or other types of conveyors,and acts as a connector to pneumatic transferring tubing. Due to the special structure of the valve as well as the application of engineering materials, it is always a very economic and effective choice.

Characteristics:
1. RIG****1 butterfly valve can be selected from two connection ways, both top and bottom are round flanges called double flange connection or a top single flange connect with a folding part which applicable to flexible tubing connection.
2. The valve bodies making use of the gravity irrigation, have a higher intensity than that of the pressure casting valves. 
3. Rotary valve plates are made of polymer materials that are resistant to wear and tear. 
4. Less components, light in weight, convenient to carry and transport. 
5. Simple to assemble and easy to maintenance 
6. No left over after transferring the materials.
7. Large numbers of stocks with a diameter between Φ*0 to Φ**0, various driving modes including manual and pneumatic can be choosed from.
