Yuken Type CRG CRNG CVT Check Valve | CVT-03 CRG-06 CRNG-10 | Subplate & Threaded

Yuken Type CRG, CRNG & CVT Series Industrial Hydraulic Check Valves

Product Overview: The Yuken Type Check Valve Series (CRG, CRNG, CVT) represents the benchmark for unidirectional flow control in hydraulic systems. This series caters to diverse installation requirements: the CRG/CRNG models feature a standard subplate mounting design for manifold integration, while the CVT series offers a threaded-in connection for flexible in-line plumbing.

This category provides full-specification support for nominal sizes 03 (3/8″), 06 (3/4″), and 10 (1-1/4″), as well as the specialized 04 size. Featuring precision-ground poppets and robust valve bodies, these valves are widely utilized in injection molding machines, hydraulic presses, machine tool HPUs, and automated production lines.

Key Technical Advantages:

• Low Pressure-Drop Engineering: Optimized internal flow paths maintain minimal pressure loss even at high flow rates, enhancing overall system energy efficiency.

• Zero-Leakage Integrity: Poppets and seats are crafted from high-strength alloy steel and precision-honed to ensure an absolute seal in the reverse direction, preventing fluid backflow under high back-pressure.

• Versatile Mounting Options: * CRG/CRNG Series: Ideal for subplate integration, reducing piping and potential leak points.

  • CVT Series: Direct in-line threaded mounting for a compact and convenient setup.

• High-Response Cracking Pressure: Available with various spring options (e.g., 0.05 MPa or higher) to meet the sensitivity requirements of different hydraulic circuits.
