DESCRIPTION
A screw-in, cartridge-style, priority-on-demand, pressure-compensator with a static load sense,
intended to provide priority flow in the required amount, while allowing excess flow to be used for
auxiliary functions.
OPERATION
The EC16-42 is a priority-type valve delivering pump flow at port 3. Port 4 will deliver required priority flow regardless of load pressure. Excess flow exits at port 2. Port 1 is the load sense port. All ports may be fully pressurized.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry-common cavity.
