Yuken Type CRG Series Subplate Mounted Check Relief Valves

Product Overview: The CRG Series Check Relief Valve is a high-efficiency pressure control component designed for hydraulic circuits that require limiting the maximum system pressure while allowing free flow in the reverse direction. Featuring a subplate mounting design that complies with international industrial standards, these valves are easily integrated into hydraulic stations and manifold blocks.

This category features high-demand industrial models: CRG-03 (3/8″), CRG-06 (3/4″), and CRG-10 (1-1/4″), including specialized configurations such as CRG-06-50-50 and CRG-06-04-50. Renowned for superior pressure stability and low pressure drop, the CRG series is the premier choice for injection molding machines, hydraulic presses, machine tool clamping systems, and automated production lines.

Key Technical Advantages:

• Dual-Function Integration: Combines relief and check functions in a single body. The relief function provides precise pressure limiting via an adjustment bolt, while the check function ensures unrestricted reverse flow through a large-diameter poppet.

• Superior Sealing Integrity: Hardened and precision-ground spools ensure an exceptional seal before the set pressure is reached, minimizing internal system leakage.

• Compact Subplate Architecture: Eliminates complex piping connections, reducing potential leak points and allowing for rapid replacement and maintenance without disturbing system plumbing.

• Versatile Pressure Regulation: Engineered to handle diverse conditions, from low-pressure control up to 21 MPa industrial high-pressure applications.
