EC16-43 Valve

EC16-43 Valve symbol


A screw-in, cartridge-style, priority-on-demand, pressure-compensator with a dynamic load
sense, intended to provide priority flow in the required amount, while allowing excess flow to be
used for auxiliary functions.

With inlet flow at port 3, the EC16-43 will deliver required priority flow at 4, regardless of load
pressure. Excess flow exits at 2. Port 1 is the load sense port. All ports may be fully

• Priority-on-demand
• Dynamic load sense
• Hardened parts for long life.
• Quiet, modulated response.
• Industry-common cavity.

Operating Pressure: 240 bar (3500 psi) maximum
