Yuken Type CRG Series Subplate Mounted Pilot Check Valves

Product Overview: The CRG Series Pilot Controlled Check Valve is a critical component for reliable load-holding in industrial hydraulic systems. Designed for subplate mounting, these valves allow free flow in one direction and controlled reverse flow when pilot pressure is applied. This category features premier high-flow models: CRG-03-04-50, CRG-06-04-50, and CRG-10-04-50.

These valves are the top choice for heavy-duty presses, metallurgical machinery, injection molding clamping circuits, and lifting equipment. The precision-honed poppet ensures a zero-leakage seal under high pressure, effectively preventing unwanted actuator drift or cylinder movement.

Key Technical Advantages:

• High-Flow Subplate Design: Compliant with industry-standard mounting patterns, providing robust installation for heavy-duty systems with high flow rates and vibration.

• Elite Sealing Integrity: Hardened poppets paired with precision metal seats guarantee zero internal leakage even during long-term pressure-holding cycles.

• Sensitive Pilot Control: Optimized pilot ratios ensure the main poppet opens rapidly and smoothly upon receiving pilot pressure, minimizing hydraulic shock.

• Industrial Durability: Rated for operating pressures up to 25 MPa, making it suitable for the most demanding high-pressure industrial environments.
