HEC32-43 Pressure Compensator (HEC32-43)
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.
Product Operation
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.
Product Features
• Hardened parts for long life.
• Quiet, modulated response.
