Parker Hannifin receives low emissions certification for industrial ball and needle valves

year option. The contracts are due to commence between Q1 and Q3 2022. Andrew Wallace, Miros’ VP Offshore Solutions, said: “We are thrilled to expand our services further to Subsea 7 by equipping Miros WaveSystem to the Seven Waves, Seven Rio, and Seven Sun vessels.” “This is a testament to Miros’ expertise and reliability in delivering accurate wave measurements via our cloud based graphical user interface Miros app. Providing Subsea 7 access to real time wave and current data, which can be shared across departments is an important function for both onshore and vessel-based personnel and key to achieving a stem sealing system leak rate of 1.2 x 10 -6 and a test of 205 cycles at a test temperature of +160°C, achieving a stem sealing system leak rate of 1.0 x10 -6 . The H series needle valve successfully completed a test of 205 cycles at room temperature, achieving a stem sealing system leak rate of 2.0 x10 -6 . Both valves were tested using Helium as the test media. Parker’s Hi-Pro high-performance Class C ball valves offer full cold working pressure ratings up to 414 bar, giving 100 per cent bubble-tight shut-off and continuous repeatable performance. Featuring a true two-piece, quality assured design, body leakage paths are reduced to a minimum. The same quality and reliability is available from Parker’s H series Class C needle pattern hand valves, which allow precise flow regulation for a wide variety of media in low-flow applications. As standard, the needle valves have metal-to-metal seats to ensure 100 per cent bubble tight shut-off. Both valve series feature fully integrated tube connections utilising either Parker’s superior advantage of proprietary A-LOK ® (two-ferrule) or CPI™ (single ferrule) fitting technologies. This important technical feature not only

Miros Group has secured a trio of three year agreements with Subsea 7 to install its internet of things (IoT) dry-sensor WaveSystem. As part of project requirements for the monitoring of wave and current to a water depth of 10m, WaveSystem will be installed on three of Subsea 7’s pipelay support vessels – Seven Waves, Seven Rio and Seven Sun – alongside access to Miros Cloud services delivering real time sea state data. The award for Miros follows an agreement between Subsea 7 and Petrobras in Brazil for new long term, day-rate vessel contracts. Each contract comprises a three year period plus a subsequent one Parker Hannifin, a motion and control technologies company, has unveiled a series of valves tested to ISO 15848-1 Class C, a standard that sets out the measurement, test and qualification procedures for fugitive emissions from industrial valves. The Class C valves complement Parker’s existing solutions for the more stringent Class A and B leak rate designations, while minimising investment required by the customer. For companies operating in the chemical, petrochemical or natural gas industries, the reasons for minimising emissions to the atmosphere from industrial valves include environmental targets, government regulations and plant/worker safety. An independent test house witnessed and certified the full factory tests accordingly. To achieve ISO 15848-1 Class C certification, a valve must demonstrate less than a certain leak rate over a predefined number of operations (cycles). Furthermore, the valve must remain within this limit while enduring predefined temperature fluctuations. Both Parker Hi-Pro ball valves and H series needle valves met the criteria and now carry certification to ISO 15848-1 Class C. The Hi-Pro ball valve successfully completed a test of 205 cycles at a test temperature of -50°C,

facilitates rapid installation, but also eliminates the need for taper threads and thread sealant and, in turn, the potential for an external leak path. This can further reduce overall plant emissions. Another technical feature of the valves that supports ISO 15848-1 Class C accreditation is a robust design of packing around the stem. The stem within industrial valves is a moving part, so a sturdy surrounding sealing concept is critical to prevent leaks during motion and in enduring the number of cycles and temperature fluctuations set out in the ISO 15848-1 Class C standard. With this development, process plants, system integrators and natural gas distributors can take advantage of Parker ISO 15848-1 Class C certified ball and needle valves that help to minimise emissions and increase safety.
