HCG Series Hydraulic Directional Control Valves with Check Valve

Product Overview: The HCG series consists of high-reliability directional control valves engineered for sophisticated hydraulic circuits. The defining feature of this series is its integrated architecture, which typically combines directional spool control with an internal check valve function. This prevents backflow and ensures the stability of actuators (such as cylinders or motors) during switching transitions. Ranging from the compact HCG-03 to the high-capacity HCG-10, the series handles operating pressures up to 25 MPa. For 2026 industrial lifting platforms, injection molding auxiliary systems, and CNC hydraulic units, the HCG series is highly regarded for its low internal leakage and space-saving design.

Featured models: HCG-03, HCG-06, HCG-10, and HCG-06-C1-22.

Key Technical Advantages:

• Integrated Check Valve Function: The unique internal design manages flow direction while providing check valve protection, simplifying circuitry and reducing system pressure drop.

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

• Tiered Pressure Ratings (C1/C2): The C1 rating is optimized for standard high-pressure operations, ensuring precise switching reliability at pressures between 21-25 MPa.

• Optimized -22 Design Sequence: The -22 designation represents the latest engineering iteration, featuring improved sealing to minimize heat loss and internal leakage during high-frequency operation.

• Versatile Electrical Control: Compatible with various AC/DC solenoid configurations and equipped with manual overrides for reliable performance in diverse industrial power environments.
