Parker EW101 series directional valve power amplifierThe Parker EW101 series directional valve is equipped with a power amplifier for controlling pilot operated proportional directional valves with displacement sensors. The flow direction of oil in the valve core can be determined by the preset command signal voltage. The stroke of the valve core and its reversing speed can be adjusted through a potentiometer. The motion characteristics of the valve core are regulated by the closed-loop feedback loop of the module. |

Parker A-series piston accumulatorThe Parker A-series piston accumulator is suitable for hydraulic applications in construction machinery, such as steering and braking systems and load damping applications. Its unique "V" - shaped O-ring sealing system maintains full pressure in load balancing applications, while its end threaded structure simplifies maintenance and minimizes downtime. The A-series accumulator is a compact and sturdy design that has been proven in thousands of applications worldwide. The wide range of inner diameter/stroke combinations ensures the ability to select appropriate volume specifications and optimize available space, while the selection of metric and imperial installation and oil port types simplifies connections. The A-series piston accumulator and B-series gas cylinder can provide two different rated pressures to accommodate maximum working pressures of 250 and 350 Bar. The same high-quality design and technical features result in optimal performance and service life for each model, while different wall thicknesses are suitable for working pressures of 250 or 350 Bar, allowing designers to accurately specify the correct application performance curve. |
