DESCRIPTION
A screw-in, cartridge-style, pressure-compensating element, intended for use with a remote fixed or variable orifice to yield a three-port, bypass-type, pressure-compensated, flow regulating hydraulic valve.
OPERATION
The EC42-M40 maintains a constant flow rate from 3 regardless of load pressure changes in the circuit downstream of 3.
The cartridge maintains a constant differential pressure from circuit point P to port 3 (see valve 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 first to 3, then bypassing excess to 2. All ports may be fully pressurized.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry-common cavity.
