Among the essential requirements for control valves used in aseptic applications, such as the food, beverage and brewing industries is a smooth, cavity-free body design without crevices or ‘traps’ and to be self-draining. This eliminates the potential for bacteria growth and also helps to ensure effective CIP and SIP (Clean or Sterilised In Place).
SAMSON CONTROLS offer a range of valves incorporating these features which are manufactured to quality assurance systems certified to ISO 9001 and also meet stringent FDA requirements. For example, their type 3347 control valve has polished steel parts to ensure the highest purity for the process medium, special PTFE bushing along with an additional steam line connection that is used to meet very stringent purity requirements preventing bacteria from spreading at the actuator stem guide.
Flowserve Corporation (NYSE: FLS), a leading provider of flow control products and services for the global infrastructure markets, and S&A Abahsain Co. Ltd., one of the top 50 business entities within Saudi Arabia, last week formally inaugurated a new valve manufacturing plant and training center in the Dammam Second Industrial City during an on-site ceremony.
The Dammam manufacturing plant is a state-of-the-art, 55,000 square foot facility with capabilities for component machining, valve assembly, and testing. The facility is operated by Flowserve Abahsain Flow Control Company Ltd., a joint venture between Flowserve Corp. and S&A Abahsain Co. Ltd.
When liquids handling applications require precise and reliable flow control of low flow rates, especially where operating conditions are particularly challenging, Badger Meter control valves are an ideal choice. Available from liquids handling specialists PUMP ENGINEERING this extensive range includes models such as the RC200.
A control valve positioner package available from valve specialists SAMSON CONTROLS is the ideal solution to the problems sometimes associated with achieving precise control of large valves. For example, in most process control applications, larger valves tend to be fitted with pneumatic actuators which provide significant positioning forces. In these situations the positioner is used to precisely position the valve by filling the actuator with the corresponding amount of air, or by venting from the actuator.
Severe service trim capabilities, cryogenic construction and a PSA version added to the general purpose valve range
Emerson announces several new capabilities for the Fisher® GX control valve and actuator system range which make it suitable for a wider range of applications. These include the addition of a Whisper Trim™ III low noise trim and an anti cavitation trim, making the valve system suitable for severe service applications. There is also a cryogenic version which enables use down to -196º C and a design specifically for use in Pressure Swing Adsorption (PSA) skids. To verify cycle life, the PSA design has been successfully tested to withstand over 1 million high speed cycles.
NAM maximises gas production and centralises control of production using Emerson’s Fisher® control valves and AMS ValveLink™ predictive maintenance software
Emerson Process Management has successfully completed a long-term project to help NAM (Nederlandse Aardolie Maatschappij) upgrade controls at its Groningen gas field in The Netherlands. More than 1000 of Emerson’s Fisher® control valves help NAM control deliveries from individual well clusters to maximise output from the field.
Complete selection tool for all intelligent automated process valves
Metso has released Nelprof 6 valve sizing software. The new version extends earlier Nelprof™ versions with two new calculation modules, which enable the selection of intelligent automated on/off valves and emergency valves. Special safety requirements, such as an actuator-sizing safety factor or a complete valve-assembly safety-integrity level, can be evaluated with the new state-of-the-art tools in the program.

This month we see the release of a further development carried out by Forac on the F series valve actuator, which as a stand-alone unit can now encompass a number of items to aid the control of valves.
Size and weight have a direct bearing on any products material costs, an important feature in the current competitive market. The F series actuator was already the smallest for its power in the world and with the F series plus it becomes the most compact control unit of its type available today.
Fisher Control-Disk valve now also available in sizes NPS 14 to 24 and ASME Class 150 & 300
Emerson Process Management has extended the line sizes for the Fisher® Control-Disk™ valve. The Control-Disk valve offers excellent throttling performance and is ideal for applications that involve fast processes and varying pressure drops, such as in the hydrocarbon, refining, chemical, pulp and paper, and metals and mining industries.
FIELDVUE digital valve controllers easily integrate with all process control host systems
Emerson’s Fisher® FIELDVUE digital valve controllers with HART and FOUNDATION fieldbus communications can now be integrated into any process control system that supports FDT/DTM technology. Using ValveLink™ DTM software, users can communicate with any FIELDVUE digital valve controller, to perform start-up, commissioning and diagnostic activities.
