Overview
The Parker FG3PKCB is a base-mounted hydraulic flow control valve designed for precision metering of fluid flow in industrial hydraulic circuits. With 3/4 JIC inlet connection and compact mounting base, the FG3PKCB enables one-way flow control with metered return, making it ideal for machine tools, presses, cylinders, and other applications requiring consistent pressure-compensated or fixed-orifice flow regulation. This used unit is fully functional and tested, providing cost-effective spare inventory for system integrators and maintenance teams.

- Pressure ranges up to 3000–5000 PSI (typical for Parker flow control valves)
- Mineral oil and compatible synthetic hydraulic fluids
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. Direct replacement compatibility depends on manifold cavity profile, porting configuration, and pressure/flow specifications of the original valve. Common Parker flow control models in similar sizes include F, FG, and PCM series units—consult Parker documentation or contact a distributor for specific model interchange.
