EC12-32 Valve

EC12-32 Valve symbol


A screw-in, cartridge-style, load sense, flow-on-demand pressure-compensator.

With inlet at port 2, the EC12-32 will deliver required flow at 3, regardless of load
pressure sensed at 1. An orifice is recommended for installation in the load-sense
line at 1 for improved stability.

• Choice of compensator springs
• Hardened parts for long life.
• Quiet, modulated response.
• Industry-common cavity.

Operating Pressure: 241 bar (3500 psi) maximum
Flow Rate: 57 lpm (15 gpm) with 5.5 bar (80 psi) compensating spring;

   83 lpm (22 gpm) with 11 bar (160 psi) compensating spring
   114 lpm (30 gpm) with 15.2 bar (220 psi) compensating spring.
Maximum Internal Leakage: 49 ml/min (3.0 cu.in./min.) at Port 1 with 241 bar
   (3500 psi) pressure at Port 2 (Port 3 blocked).
