DESCRIPTION
A screw-in, cartridge-style, flow-on-demand, pressure-compensator with load sense.
OPERATION
With inlet at port 2, the HEC12-32 will deliver required flow at 3 in response to load differential pressure sensed at 1.
FEATURES
• 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%
