Technical Notes:

Double Eccentric Design: The shaft is offset from both the centerline of the disc and the body, reducing seat wear during operation.
Extended Stem: Allows the actuator to be positioned above ground while the valve body remains buried. The stem extension is sealed to prevent ingress of moisture and soil.
Buried Coating: The coal tar epoxy provides a durable barrier against galvanic corrosion and soil stress .
