DESCRIPTION
A screw-in, cartridge-style, load sense, flow-on-demand pressure-compensator for
use in high pressure applications.

OPERATION
With inlet flow at 2, the HEC16-32 will deliver required flow at 3, regardless of load pressure
sensed at 1. For greater stability, it is recommended to install a 0.53 mm (0.21 in) orifice in
the load sense line at port 1.

FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry-common cavity
• 80 and 160 compensating springs. .
• All HyPerformance products are tested to the rigorous standards of the NFPA specification
  T2.6.1 and are tested at a verification level of 90% and an assurance of 99%.
