HEC32-43 Valve

HEC32-43 Valve symbol


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.

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.

• 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%
