Sun Hydraulics FDCBLANW5G Valve

Sun Hydraulics FDCBLANW5G is a cartridge-style, fully adjustable, pressure-compensated flow control valve with a reverse-flow check. Designed to regulate hydraulic flow with precision, it works in both meter-in and meter-out configurations, helping stabilize actuator speeds across varying load pressures. The valve's pressure-compensated design maintains more constant flow as system pressure changes, while the built-in reverse-flow check protects the downstream side from backflow during pressure transients. In verified specs, the FDCBLAN family provides a very low leakage when shut off—minimum 0.2 gpm (0.8 L/min)—supporting predictable off-state behavior in low-leakage circuits. This model is part of Sun's cartridge-based flow-control lineup, enabling straightforward installation into Sun-compatible manifolds and common hydraulic circuit configurations. Typical uses include speed control of hydraulic cylinders in machine tools, presses, and automated equipment, where precise metering and backflow protection are essential for repeatable motion and safe operation. For designers, the FDCBLAN family offers compact packaging and compatibility with standard Sun hardware, simplifying cartridge substitution and system upgrades without sacrificing performance.
