DESCRIPTION
A screw-in, cartridge-style, priority-on-demand, pressure-compensator with a static
load sense, intended to provide priority fl ow in the required amount, while allowing
excess fl ow to be used for auxiliary functions.
OPERATION
With inlet fl ow at ➂, the EC10-42 will deliver required priority fl ow at ➃, regardless of
load pressure. Excess fl ow exits at
➁. Port ➀ is the load sense port. All ports may be
fully pressurized.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry common cavity.
