For example, a cone valve attached to the discharge of a centrifugal pump may be so connected that it functions and serves as a check valve, closing when the pump stops; then, when the operator starts the pump, the valve stays closed while the pump is building up pressure, gradually opening to the full diameter of the pipe as the pump pressure reaches that of the rising main; and when the pump stops, the valve closes at a diminishing rate so water hammer is reduced to a minimum, avoiding damage.
