Higher closure efficiency – Since there are three butterfly discs instead of one, they are able to close more tightly against the valve seat and seal more effectively. This reduces leakage when the valve is closed.
Greater range of actuation – The triple eccentric design allows the discs to open and close over a wider range of motion compared to a standard butterfly valve. This provides more control over flow regulation.
Reduced friction – Each disc only has to rotate a smaller angle to fully open or close the valve. This reduces friction and wear on the discs and shaft.
Increased reliability – The triple eccentric butterfly valve factory triple disc design acts as a backup in case one disc fails. The other two discs can still provide flow regulation and closure.
Lower torque requirement – Since each disc only has to rotate a portion of the full range, less torque is required to actuate the valve. This allows for smaller, less expensive actuators.
Better sealing for viscous fluids – The additional discs help squeeze out any residual fluid trapped in the valve seat, providing better shutoff for thick or sticky liquids.
