A screw-in, cartridge-style, priority-on-demand, pressure compensator with dynamic load sense intended to provide priority flow in the required amount, while allowing excess flow to be used for auxiliary functions.
With inlet flow at port ➂, the HEC32-43 will deliver required priority flow at port ➃, based on the size of the external orifice, regardless of load pressure. Excess flow
exits, or is bypassed, at port ➁. Port ➀ is the load sense port. All ports may be fully pressurized.
• Hardened parts for long life.
• Quiet, modulated response.
