DE-FCC ADJUSTABLE FLOW CONTROL VALVE, PRESSURE COMPENSATED
DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, pressure compensated, ow control valve.
OPERATION
The DE-FCC maintains a constant ow rate out of (1) regardless of load pressure changes in the circuit
downstream of (1). The adjustable control orice can be set to customer ow specication (see options for
ranges). The valve begins to respond to load changes when the ow through the valve creates a pressure
differential across the control orice. Consult chart to see regulation at high and low adjustment settings. 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.
