HydraForce RV3 RV5 SBV11 Series Cartridge Valve | RV3-10-S-0-36 SBV11-10 | Solenoid Relief Valve

Chengyuan Hydraulic offers a comprehensive line of screw-in cartridge valves fully compatible with HydraForce industrial standards. This selection features the RV3/RV5 direct-acting relief valves and the SBV11 bidirectional solenoid valves. Engineered as highly integrated components, they are essential for custom manifold systems. We utilize high-strength alloy steel subjected to vacuum heat treatment to ensure exceptional fatigue resistance under frequent switching and high-pressure surges. All valves undergo 100% simulated condition testing, ensuring 100% original-place interchangeability while maintaining peak response precision and system stability.

Technical Specifications :

• Internal Leakage: $\le 5\text{ drops/min}$ at rated pressure

• Response Time: $\le 50\text{ ms}$

Key Technical Advantages:

• Precision Lapped Spools: The spool and sleeve are lapped in pairs with micron-level clearances. This drastically reduces internal leakage and ensures high linearity and repeatability in pressure regulation.

• Corrosion-Resistant Coating: Valve surfaces are plated with an eco-friendly Zinc-Nickel alloy, surpassing $240\text{ hours}$ of salt spray testing. This prevents spool sticking caused by rust in harsh outdoor environments.

• Compact High-Power Density: The screw-in cartridge design significantly reduces the footprint of hydraulic manifolds. The RV3 and RV5 series provide robust overpressure protection within a very small spatial envelope.

• Heavy-Duty Solenoid Coils: SBV series coils are IP69K rated for moisture and temperature resistance, supporting $100\%$ duty cycles without risk of burnout.

Application Areas:

• Mobile Equipment: Auxiliary circuit relief in excavators and pilot system unloading in loaders.

• Industrial Manifolds: Compact hydraulic power units (HPUs) and customized integrated systems.

• Agricultural Machinery: Cylinder speed control in harvesters and seeder lift protection.

Expert Maintenance Tips:

• Torque Specification: Cartridge valves are sensitive to installation torque. Always use a torque wrench (e.g., $34\text{–}41\text{ N}\cdot\text{m}$ for VC10). Overtightening can deform the sleeve and cause the spool to stick.

• Seal Integrity: Before installation, inspect O-rings and apply a thin layer of clean hydraulic oil to prevent shearing the seals during insertion.

• Contamination Control: Due to tight internal clearances, maintain system filtration at $10\mu\text{m}$ or better to prevent premature wear or malfunction.
