FLOW CONTROLS
EC16-42 Pressure Compensator,
DESCRIPTION
A screw-in, cartridge-style, priority on-demand, pressure-compensating element
intended to provide priority fl ow in required amount while allowing excess fl ow to be
used for auxiliary functions.
OPERATION
The EC16-42 is a priority-type valve delivering pump fl ow at port ➂. Port ➃ will deliver
required priority fl ow regardless of load pressure. Excess fl ow exits at port
➁. Port ➀
is the load sense port. All ports may be fully pressurized.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry common cavity.
