We supply ring butterfly valves in the RDB-L, RDO, RDE and RDB-S series. Depending on the requirements, materials such as grey cast iron, nodular cast iron, steel and stainless steel are used.
A ring butterfly valve is a valve used to control the flow of liquids or gases in a pipeline. Unlike other types of butterfly valves, the annular butterfly valve has an annular opening that regulates the flow.
Annular butterfly valves are often used in applications where precise flow is required, such as in the chemical industry, food and beverage industry or pharmaceutical industry. They can also be used in HVAC (heating, ventilation and air conditioning) systems to control the flow of air.
Ring butterfly valves are usually very reliable and require little maintenance as they have a simple design and few moving parts.
