Yuken RG Series Pressure Reducing Relief Valve | RG-03-3-32-PG RG-06 RG-10 | Hydraulic Control Valve

Yuken Type RG Series Pilot-operated Pressure Reducing and Relief Valves

Product Overview: The RG Series Pressure Reducing and Relief Valve is a high-performance composite control valve designed for systems requiring a constant branch circuit pressure despite fluctuations in the primary line. The RG model combines Pressure Reducing (output control) and Relief (overpressure protection) functions in a single unit. This category highlights core models: RG-03-3-32-PG, RG-06, RG-10, and the complete RG-03-1/2/3 configuration range.

These valves are widely used in CNC machine tool clamping circuits, industrial press branch controls, and various automated hydraulic power units. Featuring a PG (Pressure Gauge) port, it allows users to monitor real-time pressure settings, making it an ideal choice for precision pressure management.

Key Technical Advantages:

• Dual Protection (Reducing & Relief): When the branch pressure exceeds the set value, the valve automatically functions as a relief valve, effectively preventing system overload.

• High-Precision Regulation: The pilot-operated design ensures minimal pressure override and maximum stability even under fluctuating flow conditions.

• Inline Threaded Architecture: Classical threaded connections allow for flexible installation and simplified maintenance without complex manifolds.

• Comprehensive Range: Available in sizes 03 (3/8″), 06 (3/4″), and 10 (1-1/4″) to handle everything from precision control to high-flow unloading.
