DT, DG, BT & BG Series Hydraulic Pressure Control Relief Valves

Product Overview: This comprehensive range of pressure control valves covers solutions from direct-operated (DT/DG) to pilot-operated (BT/BG) relief valves. Designed to protect hydraulic systems against overpressure or maintain constant system pressure through regulation, these valves are industry staples. The DT/BT series utilizes threaded connections for flexible installation, while the DG/BG series features subplate mounting, complying with international interface standards for manifold integration. Known for high sensitivity and stability, they are widely used in machine tools and heavy industrial machinery.

Featured models include: DT-01, DG-01, DG-02, BG-03, BT-06, and BT-10.

Key Technical Advantages:

• Precise Pressure Regulation: Optimized spring grading ensures minimal pressure deviation even under varying flow conditions.

• Flexible Mounting Options: * T-Series (Threaded): Direct line mounting, ideal for simple circuits with limited space.

  • G-Series (Subplate): Modular or subplate mounting for easy replacement and reduced leak points.

• Low-Noise Operation: Pilot-operated models (BT/BG) feature optimized internal flow paths to significantly reduce whistling sounds during high-pressure relief.

• Rugged Construction: High-strength cast iron bodies with precision-ground components ensure long-term sealing integrity under high-pressure loads.
