CHIA WANG RV Relief Valve | RV-03G-3-50 | RV-06G-2-50 | Pilot Pressure Valve

CHIA WANG RV Series Pilot Operated Relief Valves

Product Overview:

The CHIA WANG RV Series is a high-performance pilot-operated relief valve specifically engineered for pressure regulation and overload protection in hydraulic systems. Its primary function is to maintain constant system pressure and safely vent excess flow when the preset value is reached. Available in G03 (3/8″) and G06 (3/4″) sizes with subplate mounting, the RV series utilizes a precise pilot architecture to ensure minimal pressure override even under high-flow conditions. Renowned for its rapid response and long-term stability, the RV series is widely used in machine tools, injection molding machines, and heavy-duty industrial presses.

Featured models on this page: RV-03G (1/2/3)-50 and RV-06G (1/2/3)-50 series.

Key Technical Advantages:

• Precision Pilot Modulation: Two-stage pressure regulation ensures smaller pressure fluctuations and lower noise levels compared to direct-acting valves during high-flow operation.

• Graduated Pressure Selections: Available in -1 (Low), -2 (Medium), and -3 (High) spring ratings, accurately covering a range from $7\text{ bar}$ to $250\text{ bar}$.

• Subplate Mounting Design: Compliant with international installation interface standards, allowing for rapid integration and replacement on hydraulic manifolds.

• Heavy-Duty Castings: Constructed from high-strength cast iron with hardened and ground internal components, ensuring maximum reliability within the 50 Design Series.
