1 SECION ILE HEC2003/2004 SERIES SERVO VLVE SYSEM he HEC2003/2004 Series Servo System features a high response servo valve, a manifold mounted filter, and three different mechanical mounting options. he manifold can feature either SE or metric straight thread ports and an optional ball valve with a locking handle. he valve offers a spool position feedback signal that can be used for system diagnostics. he HEC2003/2004 Series Servo System is directly driven by Fife s family of electronic controllers, eliminating the need for a separate drive card. Fife offers a servo valve featuring a zero lap spool thereby eliminating dead band. he valve also has an Enable command that can place the valve in an all ports blocked position eliminating the need for a blocking valve in most applications. he HEC2003/2004 offers two different spool confi gurations enabling flows from 30 LM (8 GM) to 83 LM (22 GM). he HEC2003/2004 Series Servo System also has a pressure filter that comes with a dual mechanical/ electrical dirt indicator.
