Abstract
A blank mold valving system for supplying vacuum/counter blow air to a blank mold of an I.S. The system includes an exhaust valve displaceable between open to exhaust and closed positions, a vacuum valve displaceable between open to vacuum and open to counter blow positions, and a counter blow valve displaceable between closed and open to counter blow air positions. A control operates the exhaust, vacuum and counter blow valves in a first deenergized mode wherein the exhaust valve is in the open to exhaust position, the vacuum valve is in the open to counter blow position, and the counter blow valve is in the closed position; in a second vacuum mode wherein the exhaust valve is in the closed position, the vacuum valve is in the open to vacuum position, and the counter blow valve is in the closed position, and in a third counter blow mode wherein the exhaust valve is in the closed position, the vacuum valve is in the open to counter blow position, and the counter blow valve is in the open to counter blow position.
