DESCRIPTION
A screw-in, cartridge-style, priority-on-demand, pressure-compensator with a dynamic load
sense, intended to provide priority flow in the required amount, while allowing excess flow to be
used for auxiliary functions.

OPERATION
With inlet at port 3, the EC10-43 will deliver required priority flow at 4, regardless of load
pressure.
Excess flow exits at 2. Port 1 is the load sense port. All ports may be fully pressurized.

FEATURES
• Priority-on-demand.
• Dynamic load sense.
• Hardened parts for long life.
• Quiet, modulated response.
• Industry-common cavity.
