EC50-43 Pressure Compensator, High Pressure (EC50-43)

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.

Product Operation

With inlet flow at ➂, the EC50-43 will deliver required priority flow at ➃, regardless of load pressure. Excess flow exits at ➁. Port ➀ is the load sense port. All ports may be fully pressurized.

Product Features

• Hardened parts for long life.
• Quiet, modulated response.
• Industry common cavity.
