Shutdown valveactuator

Series 825YA Reduced Pressure Zone assemblies feature a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. Activated through an add-on connection kit, the sensor can trigger the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication.This series prevents the reverse flow of contaminated water caused by backsiphonage or backpressure from entering the potable water supply. Ideal for protection at health hazard cross-connections in water services to industrial plants, hospitals, morgues, mortuaries, and chemical plants. Applications also extend to irrigation systems, boiler feeds, water lines, and other installations requiring the highest level of mechanical protection. End connection specified NPT ANSI/ASME B1.20.1.To learn more visit: https://www.watts.com/floodprotectionsystem

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 that allows a flow of material to pass through the valve while the valve is otherwise in a fully closed position.

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. 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 be otherwise operating normally. Because testing of emergency shutdown valves occurs when a facility would otherwise be operating normally, testing often results in the loss of valuable production time. Because emergency shutdown valves are often present in large-scale industrial manufacturing processes, this lost production may be associated with significant lost revenue.
