DESCRIPTION
A screw-in, cartridge-style, pressure-compensating element, intended for use with a
remote fixed or variable orifice to yield a two-port-type, pressure-compensated, flow
regulating hydraulic valve.

OPERATION
The EC10-30 maintains a constant flow rate from 2 regardless of load pressure changes in
the circuit downstream of 2.
The cartridge maintains a constant differential pressure from circuit point P to port 3,
thereby regulating the hydraulic flow rate between the two points in the circuit.

FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry-common cavity.
