Parker Hannifin has launched next-generation pre-compensated load sensing ( LS ) valves , as part of the VA Series , designed specifically for highly demanding mobile machinery applications . The VA Series is based on Parker ’ s existing high-end L90LS and K220LS valves that are renowned for their robustness , controllability , and flexibility . These next-generation precompensated LS valves have been substantially improved to increase modularity and to allow customer-efficient solutions . For example , they have been

designed with a focus on reducing space claim and enhancing mounting possibilities , while also optimizing channels to minimize flow losses . With a maximum flow to the work port of up to 450 l / min , the VA Series follows in the footsteps of the K220LS valve . The Series has been designed and optimized with features such as onboard electronics and readiness for Industry 4.0 or any other future demands regarding IoT and diagnostics . In addition to this , the new valve series also incorporates the latest hydraulic features – proportional counter pressure with the active refill , warm-up possibilities , plus several other performanceenhancing improvements that herald the dawn of the next generation in mobile directional control valves .

James Walker has developed and tested a unique highperformance packing ring set suitable for critical valves handling ultra-high temperatures as well as chemically aggressive and corrosive media such as molten salt . This field-tested and 3rd party-validated concept has demonstrated significantly extended valve service life as well as reduced leakage and will improve overall operational efficiency as well as health and safety in plants using molten salt technology .

Supagraf HT is a premium grade unique combination set construction comprising intermediate spacers and end rings of high temperature mechanically stable DS Pro material supported by high purity graphitebased intermediate packing rings . The graphite rings are manufactured in highperformance packing braided from high purity 98 % exfoliated dry graphite yarn with a passive corrosion inhibitor and reinforced with fine Inconel wire . The DS Pro precision cut spacers are made of state-ofthe-art material designed for electro-mechanical and thermomechanical applications with excellent resistance to heat and open flame up to 1000 ° C ( 1832 ° F ).

Retrofit3D , pioneered by IMI Critical Engineering , focuses on the engineering of bespoke drop-in replacement internal components . These include disk stacks and valve trims ( inclusive of seat and plugs ), ensuring the body of the valve can remain in situ throughout the process . The use of additive manufacturing technology represents a game-changing shift in valve replacement services . Each replacement part can be custom-made to the specific process conditions of the valve in question , in a fraction of the time , weight , and cost . Unlike like-for-like legacy component replacements , Retrofit3D components integrate IMI Critical Engineering ’ s DRAG ^® technology , which divides the

flow into a series of rightangled smaller passages . The multi-stage , multi-path DRAG ^® technology directs the medium through a tortuous path to incrementally reduce the differential pressure and increase control , preventing the root cause of the original problem from reoccurring . The service is now capable of producing drop-in replacement trims for valves up to 20 ” in diameter and can be used in a broad range of critical pipeline applications including bypass valves and large anti-surge valves . Retrofit3D produces replacement trims for valves manufactured by IMI Critical Engineering , as well as those from other valve manufacturers .
