Background A common and major problem associated with the testing of emergency shutdown valves is the very stoppage of flow that the valves are designed to produce. That is, while it is obviously required that an emergency shutdown valve stop a flow of material in a true emergency shutdown situation, testing often occurs when a facility would otherwise be operating normally and where stopping the flow of a needed material is undesirable. As a result, valuable production time may be lost as a result of testing an emergency shutdown valve. Because emergency shutdown valves are often present in large-scale industrial manufacturing processes, this lost production may be associated with significant lost revenue. A researcher at Ohio University has developed emergency shutdown valves capable of operating in a second mode that is not possible with known emergency shutdown valves. In the second mode of operation, the bypass feature is employed such that a flow of material may pass through the valve while the valve is otherwise in a fully close position. Potential/Commercial Applications

• Various industrial processes requiring a continuous flow of liquids or gas such as in oil/gas industry, chemical/pharmaceutical companies, electricity generating facilities, etc.

Benefits of Technology.

• Emergency shutdown valves can be tested without interrupting industrial processes which leads to production cost savings.

• Modifications can be implemented using existing valve manufacturing facilities.

FIGURE 1

FIGURE 1 is representative of a Butterfly Valve in a closed position which is the testing mode. While the valve is closed, the bypass orifice allows the flow to continue. The shutter and shutoff disk are operated using separate handle wheels. Thus, the bypass feature can be engaged or disabled when the valve is in the open position by rotating the shutter.
