EC42-M42 Valve

EC42-M42 Valve symbol


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 3 providing inlet flow, port 4 will deliver the required priority
flow regardless of load pressure. Excess flow exits at 2. Port 1 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 1
for better stability.

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