1. Pneumatic powder butterfly valve　Product overview

　　BLF series butterfly valve is automatic control valves developed specifically for powder/granule material for products.The valve body adopts lightweight high-pressure cast aluminum alloy, the butterfly plate is lined with cored steel wear-resistant polymeric material,and the rubber sealing ring formed of soft sealing make it very suitable for all kinds of powder/particle materials applications,especially for resistance to abrasion of materials.In need of gravity blanking or pneumatic conveying of powder/particle material handing system,BLF butterfly valves are mounted on the hopper,silo,screw conveyor outlet and a pneumatic duct.
