Yuken Style Remote Relief Valve | DT-02-C DG-02-H | DT-01 DG-01 | Pilot Operated Pressure Valve

DT / DG Series Pilot-Operated Remote Control Relief Valves

Product Overview: The DT and DG series are essential components for achieving precise pressure regulation in hydraulic systems. These pilot-operated valves typically function as the remote control stage for a main relief valve, allowing operators to fine-tune system pressure from a location distant from the main pump station. The DT series features threaded (in-line) connections, while the DG series is designed for subplate mounting, offering flexibility for various piping layouts. With optimized internal galleries, these valves maintain a constant set pressure across a wide flow range, effectively preventing system overload and reducing vibration.

Featured models: DT-02-C-22, DG-02-H-22, DT-01-22, and DG-01-3-32.

Key Technical Advantages:

• High-Precision Regulation: Equipped with precision-ground poppets and high-linearity springs to ensure smooth pressure adjustments without erratic pulses.

• Remote Control Flexibility: When used as a pilot stage, it enables remote intervention of main circuit pressure, optimizing the operational layout of large-scale machinery.

• Multiple Pressure Gradients: * C-Grade: Ideal for precise regulation in low-to-medium pressure ranges.

  • H-Grade: Engineered for high-pressure applications, providing robust system safety protection.

• Low Noise Stability: The specialized damping structure effectively suppresses shrieking noises during relief, improving the working environment.

• Compact & Durable: High-strength cast bodies combined with heat-treated internal components ensure an exceptionally long mechanical fatigue life.
