The DC5812 series triple eccentric butterfly valve has bi-directional bubble free tight closing performance. This geometric shape ensures that the valve plate seal only contacts the valve body and seat when in the closed position, so there will be no friction or wear, and a torque is generated to provide sufficient contact area for the elastic seal, similar to the conical seal of a globe valve, ensuring uniform and consistent sealing contact.
