Marine butterfly valve is approved by DNV GL. It is with enough body thickness and strong resistance of pressure, The normal pressure is up to 2.0Mpa. With only a few parts, marine butterfly valves are easily maintenance and simple operation, only need to rotate 90 ° to quickly open and close, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics
