DESCRIPTION
A screw-in, cartridge-style, load sense, fl ow-on-demand pressure-compensator.
OPERATION
With inlet fl ow at ➁, the EC12-32 willl deliver required fl ow at ➂, in response to load
differential pressure sensed at
➀.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry common cavity.
