RCT-10-F1-22UB Yuken Sequence Pressure Control Valve

Product Overview

The RG-03, RG-06, RG-10, RCG-03, RCG-06, RCG-10, RT-03, RT-06, RT-10, RCT-03, RCT-06, RCT-10 and RCT-10-F1-22UB belong to the Yuken pressure control valve series, including pressure reducing valves (RG/RCG) and sequence/pressure control valves (RT/RCT). RCG/RCT versions incorporate a check valve for free reverse flow from secondary to primary side. Fully interchangeable with original Yuken units, every valve undergoes 100% simulated operating-condition testing for reliable pressure reducing, sequencing, counterbalance or unloading functions in hydraulic systems.

Key Technical Advantages

1. Precise pressure reducing and sequencing: Direct-acting or pilot design maintains stable secondary pressure, ideal for sequential operations and load-sensitive control.
2. Optional integral check valve: RCG/RCT models allow free reverse flow, simplifying circuit design and enabling counterbalance functions.
3. High interchangeability: Identical mounting dimensions and interfaces to original Yuken RG/RCG/RT/RCT series enable direct drop-in replacement.
4. 100% functional verification under simulated conditions: Every unit is fully tested across pressure-flow characteristics before shipment, ensuring consistency and reliability.

Application Areas

• Sequential operation control in hydraulic systems
• Pressure reducing and counterbalance circuits for actuators
• Clamping and holding systems on machine tools
• Multi-pressure zone control on injection molding and die-casting machines
• Multi-stage pressure management in industrial hydraulic power units

Expert Maintenance Tips

Ensure clean interfaces and tighten to the specified torque. Maintain required fluid cleanliness to protect the spool. Adjust pressure gradually to avoid shocks. Periodically check secondary pressure stability. If pressure fluctuates, first inspect fluid contamination and pilot filtration. For long-term storage keep the valve filled with oil. Always use original-specification seals when servicing.
