DE-FCA ADJUSTABLE FLOW CONTROL VALVE, PRESSURE COMPENSATED
DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, pressure compensated, ow control valve.
OPERATION
The DE-FCA maintains a constant ow rate out of (1) regardless of load pressure changes in the circuit
downstream of (1). The adjustable control (see options for ranges) differential spring load can be set to customer
ow specication. The valve begins to respond to load changes when the ow through the valve creates a
pressure differential across the control orice greater than 100 PSI (6.9 bar), with accurate ow maintenance
from 100 to 3500 PSI (6.9 to 241 bar). Reverse ow (1) to (2) returns through the control orice and is non-
compensated. The regulated ow increases from low to high with clockwise rotation of the knob.
FEATURES
• Hardened parts for long life.
• Industry common cavity.
• Fine low-torque adjustment.
