A screw-in, cartridge-style pressure-compensating element intended for use with a remote fi xed or variable orifice to yield a three-port (bypass-type), pressure-compensated, flow regulating hydraulic valve.
The EC42-M40 maintains a constant flow rate from ➂ regardless of load pressure changes in the circuit downstream of ➂The cartridge maintains a constant differential pressure from circuit point “P” to
port ➂ (see symbol), thereby regulating the hydraulic flow rate between the two points in the circuit. The EC42-M40 is a priority type regulator, delivering pump flow
fi rst to ➂, then bypassing excess to ➁. All ports may be fully pressurized.
• Hardened parts for long life.
• Quiet, modulated response.
• Industry common cavity.
