“The Green Valve” - an environmentally friendly product.
Rotary Valves are a critical part of cleaning the pollution from a plant. The polluted air is sucked through bag filters which are then pulsed and the dust is conveyed through a Rotary Valve & ultimately a waste product which is dumped safely. There is a differential air pressure in these bag houses, and of course the Rotary Valve is an Airlock and conveys the dust without losing pressure. Join us and help provide a cleaner, safer world for future generations.
Designed with simplicity and reliability – the 4B range of rotary valves provides a broad solution to your solids handling requirements.
4B Africa has a wealth of experience in gravity flow conveying systems, and our engineers will be happy to provide advice for your application.
Manufactured in South Africa, most of our valves are available from stock.
