EC16-40 Valve

EC16-40 Valve symbol


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.

The EC16-40 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 EC16-40 is a priority
type regulator, delivering pump flow first to 3, then bypassing excess to 2. All ports may be fully

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

Operating Pressure: 240 bar (3500 psi) maximum
Flow Rate: 100 lpm (26.5 gpm) max. regulated; 180 lpm (47.5 gpm) max. input;
   Pressure at 1 begins to rise higher than compensating pressure differential
   when bypass flow exceeds 80 lpm (21 gpm)
Standard Compensator Bias Spring: 5.5 bar (80 psid)
Flow Maintenance: 7.57 to 98.4 lpm (2 to 26 gpm) settings ±10%
