10 years Emerson Exchange   In October 2012, the Emerson Global Users Exchange celebrated its 10th anniversary. And what is the best way to celebrate? A big party and that is exactly what the organizers had in mind, when they started preparing the biggest ever Exchange event. The event travels each year to a different state in the US and this time it took place in Anaheim, California. Valve World was invited to attend the conference sessions and walk the expo fl oor to bring back the best impressions of this anniversary e...
	Advances in automated subsea valves Significant steps in the global subsea oil and gas industry have pioneered new engineering techniques in both exploration and extraction. As the industry has moved into ultra deep water applications, this has presented a range of technical challenges with regards to the design and performance criteria for critical equipment, such as valve and actuation systems. Here, Pieter Kok reviews these technical challenges and the key considerations during the design process and testing procedure in ord...
	AOV Manager Marie Murphy puts safety first and foremost It may be an obvious statement but they take safety very, very seriously at nuclear power plants. Equipment and processes are continually checked to ensure the plant functions as it should. Visiting the USA, Valve World caught up with AOV Program Manager Marie Murphy to ask what her job entails....
	Developments in nuclear valve actuation technology Rotork has been involved in the supply of electric actuators for installation in nuclear power plants since the 1960s and since the 1970s the company has been a participant member of the sub-committees of the US Standards Committee responsible for drafting various IEEE 382 standards. This extensive experience of nuclear operations and nuclear qualifications is now contributing to the development of new products....
	Electric actuators in extreme environments In this technical article, AUMA’s Michael Herbstritt details the role of actuators play in extreme applications and explains how actuation technology can meet the demands of these environments. Examples provided include a copper mine in the Chilean Andes, a flood control project and a nuclear reactor....
	Five minutes with Mr Fernando Spisto In an on-going series of interviews, Valve World puts some rapid-fire questions to engineers working for end user companies and engineering contractors. In August 2008, one of Bechtel’s Senior Control System Engineers agreed to take the hotseat....
	Leveraging the power of Profibus Belgium is well-known for many of the good things in life: excellent cuisine, exquisite diamonds, sumptuous chocolates… and now the country can also boast about its superior networking solutions for infrastructure projects. So much becomes quite clear when talking to Kees Geldhof, who as Sales Engineer for AUMA in Belgium knows all about the benefits Profibus can bring....
	PM for all! During a recent trade show, Valve world had the pleasure of meeting up with Rotork's Richard Harvey, who is the Business Development Manager for SVM and SIL Applications....
	Retrofitting a refinery A previous Valve World report on AUMA’s success winning a contract to supply the BP Refinery in Rotterdam outlined the challenging requirements for electric actuation set by one of the world’s biggest energy companies. Following the installation of over 1,000 explosion-proof actuators, the manufacturer of modular actuation technology provides this follow-up article, with particular focus on how the site’s retrofit requirements were achieved....
	Safety first and foremost at AOV MOV events Valve World’s David Sear reports from the 2008 editions of the AOV and MOV annual meetings, held in Orlando, Florida. He found the events to be extremely open platforms where engineers and technicians discussed issues around the use of air and motor operated valves in nuclear power plants....
	SIPOS meets challenges of world's largest lignite plant In this case history, the author describes how SIPOS set about equipping a major lignite plant with actuator solutions....
	Subsea valve actuation - reliability in depth With an installed base dating from the early 1990s, operating at depths down to 2500 metres, Rotork Fluid Systems is familiar with supplying hydraulic actuator products to meet stringent subsea demands. Rotork’s qualified engineering group has established a range of actuators with ROV (Remote Operated Vehicle) or diver operated facilities and developed some innovative solutions for specific subsea valve operations. A brief summary of valve applications using Rotork’s actuators includes ESD (emer...
	User's Guide - Electric Actuators The electric actuator, initially designed to operate valves and dampers, has now also evolved into a maintenance and control tool. Considering the diversity of applications and the wide range of actuator options to choose from, working out the best actuator to meet your specific needs can be a complex task. This User’s Guide is an abridged version of Bernard Controls’ User’s Guide, which aims at making actuator selection as easy as possible....
	Valve actuation and control in the modern super refinery When you are operating one of the largest single refinery sites in the world, then you need a well thought out actuation strategy. One that couples superior commissioning and data transfer technologies to robust actuators with a proven track record, for example. Review of Reliance’s Jamnagar Refinery....
	Valve actuation at the world’s largest flow metering calibration facility Situated by the New Meuse River in Rotterdam, EuroLoop will be the world’s largest research and test site for flow meters. The facilities make extensiove use of electric and pneumatic actuators with sophisticated control systems....
