PB-FCA ADJUSTABLE FLOW CONTROL VALVE, PRESSURE COMPENSATED
DESCRIPTION
8 size, 3/4-16 thread, “Power” series, pressure compensated, ow control valve.
OPERATION
The cartridge maintains a constant ow rate out of (1) regardless of load pressure changes in the circuit
downstream of (1). The adjustable control differential spring load can be set to customer ow specication (see
options for ranges). The valve begins to respond to load changes when the ow through the valve creates a
pressure differential from (2) to (1), greater than 200 PSI (14 bar), with accurate ow maintenance from 200 to
3500 PSI (14 to 241 bar). Reverse ow (1) to (2) returns through the control orice 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.
