DESCRIPTION
A screw-in, cartridge-style, priority-on-demand, pressure-compensator with a dynamic
load sense, intended to provide priority flow in the required amount, while allowing excess
flow to be used for auxiliary functions.

OPERATION
With inlet flow at port 3, the HEC32-43 will deliver required priority flow at 4, based on the
size of the external orifice, regardless of load pressure. Excess flow exits at 2. Port 1 is
the load sense port. For greater stability, it is recommended to install a Ø1.09 mm (Ø0.043 in)
orifice in the load sense line at port 1. All ports may be fully pressurized.

FEATURES
• Priority-on-demand.
• Dynamic load sense.
• Hardened parts for long life.
• Quiet, modulated response.
• All HyPerformance™ products are tested to NFPA specification T2.6.1
  and are tested at a verification level of 90% and an assurance of 99%
