A screw-in, cartridge-style, load sense, flow-on-demand pressure-compensator with built-in damping and load-holding features for use in gravity-lowering circuits.
The HEC12-34 is designed to be used in combination with a flow control valve for lowering and holding a load. With inlet flow at port 2, port 3 will deliver required flow regardless of load pressure sensed at port 1.
• Hardened parts for long life.
• Hardened seat for low-leakage load-holding capability.
• Quiet, modulated response.
