Product Description

DN800 QT500 DI Double Offset Flanged Rubber Ring Butterfly Valves with Electric and Hanwheel

These types of valves can be actuated either electrically or with a handwheel, depending on the application and the preference of the user. Electric actuated valves are controlled by an electric motor, which provides precise and rapid control over the valve's position. Handwheel actuated valves, on the other hand, are operated manually by turning a handwheel. The "double offset" design of these valves means that the axis of rotation of the valve disk is located off-center from the valve seat, which reduces wear and minimizes friction as the valve operates. This design allows for a tight shut-off, which can be useful in applications where leakage must be minimized or eliminated altogether.
