Introduction about butterfly valve design standards-Belo Valve

Butterfly valves are widely used, mainly for switching and regulating in pipelines. What are the design standards for butterfly valves, how those standards are formulated, and how those standards are implemented? Those is what we are going to introduce today:

Belo Valve is a professional manufacturer and supplier for concentric butterfly valves and eccentric butterfly valves; for concentric butterfly valves, we have wafer type butterfly valves, wafer lugged type butterfly valves, concentric flange type butterfly valves. For eccentric butterfly valves, we have single eccentric butterfly valves, double eccentric butterfly valves and triple eccentric butterfly valves. 

All butterfly valves products produced by Belo Valve are designed and fabricated in strict accordance with the corresponding national and international standards, and must undergo strict quality inspection before the delivery to ensure each valve products that enter into the market meet relevant standards, and can stand the test of the market.
