Product Overview
The YUKEN UCF1G-04-30-30 is a precision-engineered flow control and check valve module from YUKEN’s UCF1G series, designed for accurate regulation of actuator speed in industrial hydraulic circuits. This modular valve combines a pressure-compensated flow control function with an integral check valve, enabling controlled flow in one direction and unrestricted reverse flow. The UCF1G-04-30-30 is a sandwich-style modular valve that mounts between a directional control valve and a subplate, providing meter-in or meter-out speed control without additional piping. Manufactured to YUKEN’s exacting tolerances, it delivers stable flow regulation independent of load and pressure fluctuations, making it a reliable choice for demanding industrial hydraulic systems.

Engineering Features & Advantages
- Precision Flow Metering: Pressure-compensated spool design maintains a constant set flow rate regardless of load variations, ensuring consistent actuator speed and repeatable machine cycles.
- Integrated Check Valve: Allows unrestricted reverse flow for rapid return strokes, eliminating the need for separate check valve components and simplifying circuit design.
- Modular Sandwich Construction: Mounts directly between directional control valve and subplate per ISO 4401 / NG10 standards, reducing piping, leak points, and installation time.
- Stable Low-Load Performance: Precision spool and sleeve clearances deliver smooth, chatter-free operation even at low flow settings and varying system pressures.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with hardened, wear-resistant internal components.
- Direct Fit Replacement: Exact dimensional and functional compatibility with YUKEN OEM standards for drop-in replacement without modification.
