With the introduction of this inverse-proportional 3-way pressure-reducing cartridge, Bucher Hydraulics has widened the range of valves that feature the compact solenoid system. The new push-in cartridges are built on the proven design principle and are available with a rising or falling (fail-safe function) pressure/current characteristic. The advantages over the previous solenoid system are smaller space requirement, 360° rotatability at installation and easy installation of the plug-in cartridge thanks to the mounting clip. The compact solenoid system also offers an ideal price/performance ratio, which is vital for reducing operating costs and capital expenditure.
