CRG Series Gasket Mounted Pilot Controlled Check Valves

Product Overview: The CRG Series Pilot Controlled Check Valve is an essential load-locking component for high-performance hydraulic systems. Designed with a gasket-mounted interface, these valves allow free flow in one direction and controlled reverse flow via an external pilot pressure signal. This category focuses on precision industrial models: CRG-03-04-50, CRG-06-35-50, CRG-10-5-30, CRG-03-50-10, and CRG-06-50-30.

Renowned for their exceptional sealing integrity, the CRG series effectively prevents actuator drift caused by gravity or external loads. Featuring robust cast-iron bodies and precision-ground spools, they are the premier choice for plastic injection molding machines, hydraulic presses, large machine tools, and automated production lines.

Key Technical Advantages:

• Elite Load Holding: The poppet-style seat ensures zero internal leakage in the reverse direction, providing stable, long-term locking force for the system.

• Minimal Pressure Drop: Optimized internal flow paths significantly reduce energy loss during high-flow operation, enhancing overall machine efficiency.

• Variable Cracking Pressures: Available with different spring settings (as indicated by model codes) to match specific pilot-control requirements and environmental conditions.

• Standard Gasket Mounting: Fully compliant with Yuken mounting dimensions for direct, hassle-free replacement on existing manifold blocks.
