Yuken H & HC Valve | HT-03-C3 | HG-06-L1 | HCT-10-N1 | HCG-10-B2 | Hydraulic Pressure Control

Yuken H & HC Series Hydraulic Pressure Control Valves

Product Overview: The Yuken H and HC series are the benchmarks for precision pressure management in industrial hydraulic systems. This versatile series covers functions ranging from basic relief and pressure reducing to complex sequencing and unloading tasks. Whether in the compact Size 03 (NG10) or the high-flow Size 10 (NG32), the 22 design sequence delivers exceptional regulation stability and an extended service life. In 2026, the H/HC series remains a staple for machine tool power units, forging equipment, and automated production lines, ensuring circuit safety and efficiency through ultra-low internal leakage and accurate cracking pressures.

Featured models: HT-03-C3-P-22, HG-06-L1-22, HCT-10-N1-22, and HCG-10-B2-22.

Key Technical Advantages:

• Full-Function Pressure Management: Available in H (Standard) and HC (with Check Valve) types, configurable as relief, reducing, sequence, or counterbalance valves.

• Tiered Sizing: Offered in 03 (NG10), 06 (NG25), and 10 (NG32) sizes, supporting flow rates in excess of 500 L/min.

• Flexible Mounting Options:

  • HG/HCG (Subplate Mounting): Ideal for manifold integration to simplify piping.

  • HT/HCT (Threaded/Inline Mounting): Directly connects to pipelines for flexible layout.

• Tiered Pressure Ratings (B/C/L/N): Optimized for specific adjustment ranges (e.g., C for mid-pressure, H/L for high-pressure), ensuring excellent linearity across the full handle rotation.

• Optimized 22 Design Sequence: Incorporates the latest 22 series standards with enhanced spool contamination resistance and optimized pilot damping characteristics.
