22 | September 2017 | VALVE TECHBOOK: TECHNOLOGY SHOWCASE Valve Controller Delivers an Improved User Experience The Neles NDX is Metso's latest addition to its comprehensive valve controller offering. The valve controller offers accurate and reliable perfor- mance in a wide range of applications, regardless of industry or the brand of valves being used. The Neles NDX offers control accuracy that will have a direct and positive effect on process variability and, subsequently, on profitability. Improved con- trol accuracy can help ensure production quality and minimize the amount of production losses. It also can assist in the optimization of raw material, chemical and energy consumption. These devices are simultaneously inspired by the latest technolo- gies and more than 50 years of experience in valve controller manufacturing. They are designed and manufactured to perform in demanding opera- tions and process conditions. The smart and dura- ble design improves safety in both installation and operation. Through-conduit Slab Gate Valves for Subsea Applications OMB is conducting an extensive R&D program, which is aimed at extending the product range to include through-conduit slab gate valves for demanding subsea applications. The targeted appli- cation for this new product is deep water to a depth of 10,000 ft and high pressure up to API 15,000 (1,034 bar) with a size range from .5 in. to 7-1/16 in. All newly developed valves will be equipped with linear subsea actuators and/or gearboxes, which is a new product line, entirely engineered, assembled and tested within OMB. An ROV interface is avail- able for all subsea assemblies as well. The Qualifi- cation of Subsea Through-conduit Slab Gate Valves is currently an ongoing project with testing equip- ment in place and testing underway. Hyperbaric testing, full PR2 qualification testing and endur- ance testing form the basis of the qualification program. All of the testing carried out is witnessed by a third-party inspection agency. International design standards together with customer specifi- cations are incorporated into the test procedures being used to qualify the valve/actuator assemblies with the objective of creating a through conduit slab gate valve range capable of meeting the most stringent industry demands. Ball Valves Offer Various Design Options Rays Flow Control's RAYS API 6D Ball Valve has a soft-seated or metal-to-metal seated design that can be applied to various working conditions and temperatures (-196 C [-321 F] lowest temperature). Top entry design can realize online repair/acces- sories replacement, reduce maintenance cost and extend service life. The integral body design could also minimize leakage point. The rising stem ball valve has no friction during the open/off process, has a self-cleaning spherical and has a stronger self-seal with more reliable sealing. The high-pres- sure pigging valve with patented design offers eas- ier sending/receiving with more safe and reliable operation. In addition, the company's new fugitive emission design is a more assured fugitive emis- sion design. Packing comes from a certified API 622 manufacturer with many options available, which depends on temperature/medium. The lip seal ring design can meet the requirements of ISO 15848/ The Neles NDX is easy to install and use.
