FLOW CONTROLS
HEC32-43 Pressure Compensator
DESCRIPTION
A screw-in, cartridge-style, priority-on-demand, pressure compensator with 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 port ➂, the HEC32-43 will deliver required priority fl ow at port ➃,
based on the size of the external orifi ce, regardless of load pressure. Excess fl ow
exits, or is bypassed, at port
➁. Port ➀ is the load sense port. All ports may be
fully pressurized.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
