They are generally used in water, drinking water and wastewater projects. Epoxy coated body material is ductile iron. The sealing of the valve is provided by a T-profile elastomeric ring secured by a pressure ring on the flap. The biaxial design reduces wear on the sealing ring and reduces torque. The sealing ring can be replaced without the need for special tools in the field and without the need to remove the clapper.
