CRG & CRT Series Industrial Hydraulic Check & Relief Control Valves

Product Overview: The CRG and CRT Series offer high-performance solutions for pressure control and backflow prevention in heavy-duty hydraulic systems. This series includes inline (CRT) and sub-plate/right-angle (CRG) designs capable of withstanding system pressures up to 31.5 MPa. This category highlights precision models: CRG-03-04-50, CRT-06, CRT-10, and configurations covering cracking pressures from 5 to 75 (0.05 to 0.75 MPa).

Constructed with high-strength materials and precision poppet designs, these valves ensure zero internal leakage during shut-off while maintaining minimal pressure drop during forward flow. They are the premier choice for injection molding machines, large hydraulic presses, machine tool power units, and automated industrial production lines.

Key Technical Advantages:

• Diverse Mounting Options: * CRT Series: Inline threaded connection, offering compact installation for constrained piping spaces.

  • CRG Series: Sub-plate/Right-angle mounting, ideal for ease of maintenance and high-flow integration.

• Precise Cracking Pressure Control: Available in a range of pre-set spring tensions from 0.05 MPa (05) to 0.5 MPa (50) or higher to meet specific load-holding requirements.

• Elite Sealing Integrity: Hardened spools and precision-ground seats guarantee long-term zero-leakage performance under high-pressure conditions.

• High-Flow Capacity: Optimized internal flow paths maintain stable system pressure even at high velocities.
