FLOW CONTROLS
EC10-30 Pressure Compensator
DESCRIPTION
A screw-in, cartridge-style pressure-compensating element, intended for use with a
remote fi xed or variable orifi ce to yield a two-port-type, pressure-compensated, fl ow
regulating hydraulic valve.
OPERATION
The EC10-30 maintains a constant fl ow rate from ➁ regardless of load pressure
changes in the circuit downstream of
➁.
The cartridge maintains a constant differential pressure from circuit point P to port
➂ (see USASI Symbol), thereby regulating the hydraulic fl ow rate between the two
points in the circuit.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry common cavity.
