DESCRIPTION

A screw-in, cartridge-style, priority-on-demand, pressure-compensator with a

dynamic 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 EC10-43 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.

Note: This valve, the EC10-43, replaces the older EC10-41 functionally,

although the two valves have different port logic. We will continue

to provide the EC10-41 for existing customers, but recommend

conversion to the new EC10-43 for new designs.
