DE-FCB FIXED FLOW CONTROL VALVE, PRESSURE COMPENSATED
DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, xed pressure compensated, ow control valve.
OPERATION
The DE-FCB maintains a constant ow rate out of (1) regardless of load pressure changes in the circuit downstream
of (1). The valve begins to respond to load changes when the ow through the valve creates a pressure differential
across the control orice, in excess of the spring load. Consult chart for regulation performance. Reverse ow (1)
to (2) returns through the control orice and is non-compensated.
FEATURES
• Hardened parts for long life.
• Industry common cavity.
