Rotork is playing a key part in the expansion of the ExplorerPipeline, a 1400 mile products pipeline that delivers petrol,diesel and jet fuel from the Gulf Coast to several midwesternUSA states and the city of Chicago. Based in Tulsa, theExplorer Pipeline owners are constructing twelve new pumpstations, modifying a further twelve existing pump stationsand building a 500,000 barrel storage terminal at Illinois inorder to increase system throughput by 47 million barrelsannually.

Over 50 years of operation wassimulated in a three month timeframe.

Part of the project involves the replacement of existing gate valves andhydraulic actuators with new ball valves and electric actuators thatoperate within 10 seconds.

Explorer decided to validate the performance of the large 24inch Class600 ball valves and Rotork IQ electric actuators by commissioning ouragent in Tulsa, Flow Quip, to conduct a comprehensive testprogramme. Flow Quip designed a PLC controlled test rig thatsimulated actual operating conditions by operating the valve against1000psi unbalanced differential pressure. The valve was cycled 44times in a two hour period with additional cycles spread over theremaining 22 hours to achieve a total of 500 operations a day. Over50 years of operation was simulated in a compressed three monthtime frame.

At the conclusion of the test programme the actuator had deliveredover 20,000 cycles and, on inspection, was found to be ready formore. IQ-Insight software was utilised during the test to monitor valveand actuator performance and develop trends for analysis. Successfulcompletion of the test led to a purchase order for more than 130Rotork IQ actuators.

Rotork valve actuators forDeviceNet open networksmeet the latest ODVAstandards

Water for New York is suppliedfrom a reservoir network that isbeing constantly upgraded andimproved. As new structuresand dams are built, ways ofmaintaining the flows into thestreams that were once fed bythe watershed are beingdesigned in order to supportthe wildlife that they maintain.In addition, a reliable andcontrolled means of loweringreservoir levels over apredictable period of time isessential to defend againstthe risk of flash flooding.

The Rotork package utilisesthe Pakscan llS sequencermaster station to monitorreservoir levels, watch overthe security of the system andcontrol the flow rate into thestreams that are being fed.

A complete picture of actuator andvalve status including valveposition, torque generated andalarms present is available to thesystem controller.

Rotork helps to monitorthe level of New Yorks water supply

The first of what is expected to beseveral Rotork installations hasnow been commissioned at theWest Branch Dam, using nine IQintelligent electric actuators toautomatically control very largegate and ball valves in response todata including signals from levelsensors. The Pakscan masterstation is housed within a Rotorkdesigned cabinet which includes adisplay monitor for the RotorkIn-Vision software that provides areal-time graphical display ofsystem status, position andavailability.

The Rotork system ensures that,irrespective of rainfall amounts,

the streams will alwayshave a water source,whilst the reservoir levelcan be maximised when

the streams do notrequire topping up.

Rotork electric valve actuators are now available with theRotork DeviceNet module, enabling them to be controlled overlow cost networks using the popular DeviceNet protocol.Rotork's design is to the latest Open DeviceNet VendorsAssociation standards and applies to our entire current rangeof multi-turn and quarter-turn electric actuators, including themodulating versions.

The Rotork DeviceNet module isfitted within the environmentallysealed actuator enclosure foroptimum reliability. The modulecan be factory fitted in new unitsor is easily retrofitted on in-serviceactuators.Direct DeviceNet connectivityprovides process controlinformation as well as importantdiagnostic data that wouldotherwise not be accessible overa conventional hardwired system.A complete picture of actuatorand valve status including valveposition, torque generated andalarms present is available to thesystem controller. In addition fourdigital outputs are provided aswell as the standard open, stop,close and emergency shut-down,whilst one general analogue inputis also available for customer

connection to an external signal.To ensure easy integration witheven the simplest DeviceNetequipped host, the data reportedfrom each actuator is containedwithin an 8 byte string and controloutput data is similarly containedwithin a 4 byte string to keep datatransactions to a minimum.
