Parker Hannifin is announcing a set of next-generation pre-compensated load sensing (LS) valves, as part of the VA Series, designed specifically for highly demanding mobile machinery applications. The market-leading performance of the VA Series mobile directional control valves ensures outstanding maneuverability and robustness, as well as allows greater flexibility and modularity. These valves are designed and prepared to meet future demands within a range of challenging industries, such as forestry, construction, mining, and material handling.
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 pre-compensated LS valves have been substantially improved to increase modularity and to allow customer-efficient solutions. For example, these valves 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 and takes the performance to the next level. The VA 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 performance-enhancing improvements that herald the dawn of the next generation in mobile directional control valves.
The VA300 is the first valve of the new series to be released. The next valve in the series, VA450, is set to be launched at the start of 2023.
