A valve body with an integral bypass comprising: a primary valve body portion defining a primary internal surface and a primary external surface, the primary internal surface defining a primary bore extending through the primary valve body portion from a primary upstream end to a primary downstream end, the primary bore comprising a primary upstream bore extending through the primary upstream end and a primary downstream bore extending through the primary downstream end, the primary valve body portion configured to house a valve member between the primary upstream bore and the primary downstream bore; and the bypass seamlessly integrated with the primary valve body portion, the bypass defining a bypass external surface and a bypass internal surface, the bypass internal surface defining a bypass bore, the bypass bore comprising a bypass upstream bore and a bypass downstream bore, the bypass upstream bore extending through the primary upstream end of the primary valve body portion from the primary external surface to the primary internal surface of the primary upstream bore, the bypass downstream bore extending through the primary downstream end of the primary valve body portion from the primary external surface to the primary internal surface of the primary downstream bore, the bypass internal surface seamlessly intersecting the primary internal surface at the primary upstream end and the primary downstream end, characterized in that, the bypass comprises an integral reinforcement web extending between a bypass upstream end, a bypass valve body, and a bypass downstream end, and in that the valve body is comprised of a monolithic casting formed from a single material. a primary valve body portion defining a primary internal surface and a primary external surface, the primary internal surface defining a primary bore extending through the primary valve body portion from a primary upstream end to a primary downstream end, the primary bore comprising a primary upstream bore extending through the primary upstream end and a primary downstream bore extending through the primary downstream end, the primary valve body portion configured to house a valve member between the primary upstream bore and the primary downstream bore; and the bypass seamlessly integrated with the primary valve body portion, the bypass defining a bypass external surface and a bypass internal surface, the bypass internal surface defining a bypass bore, the bypass bore comprising a bypass upstream bore and a bypass downstream bore, the bypass upstream bore extending through the primary upstream end of the primary valve body portion from the primary external surface to the primary internal surface of the primary upstream bore, the bypass downstream bore extending through the primary downstream end of the primary valve body portion from the primary external surface to the primary internal surface of the primary downstream bore, the bypass internal surface seamlessly intersecting the primary internal surface at the primary upstream end and the primary downstream end, characterized in that, the bypass comprises an integral reinforcement web extending between a bypass upstream end, a bypass valve body, and a bypass downstream end, and in that the valve body is comprised of a monolithic casting formed from a single material.
