A screw-in, cartridge-style priority-on-demand pressure-compensator with static load sense.
The EC42-M42 provides priority flow in the required amount, while allowing excess
flow to be used for auxiliary functions. With port ➂ providing inlet flow, port ➃ will deliver the required priority flow regardless of load pressure. Excess flow exits at ➁. Port ➀ is the load sense port. All ports may be fully pressurized.NOTE: 0.031 in. (0.79 mm) orifice is recommended to be installed in the load sense
line at port ➀ for better stability.
• Hardened parts for long life.
• Quiet, modulated response.
• Industry common cavity.
