SV5-8 SV13-10 SV13-12 Hydraulic Solenoid Cartridge Valve | Vickers HydraForce Type

The SV Series solenoid cartridge valves from Chengyuan Hydraulic are high-performance logic elements fully compatible with Vickers and HydraForce industrial standards. Specifically designed for Hydraulic Integrated Circuits (HIC), these valves provide reliable on/off control for fluid flow in a compact footprint. For core models like SV5-8-C (NC), SV13-10 (Size 10), and SV13-12, we utilize hardened alloy steel spools and high-permeability solenoid tubes. Every valve undergoes 100% simulated operational frequency and pressure testing before shipment to ensure reliable shifting under high backpressure, guaranteeing 100% original-place interchangeability.

Technical Specifications:

• Series Model: SV Series (2-Way Solenoid Cartridge Valve)

• Cavity Sizes: 08 (5/8″-18 thread), 10 (7/8″-14 thread), 12 (1 1/16″-12 thread)

• Initial State: C (Normally Closed) / 0 (Normally Open)

• Rated Operating Pressure: 210 bar (21 MPa) / Up to 350 bar for high-duty versions

• Max Flow Rates: 23 L/min (Size 08) / 45 L/min (Size 10) / 114 L/min (Size 12)

• Standard Voltages: $12V DC$, $24V DC$, $110V AC$, $220V AC$

• Power Consumption: 18W – 22W (Depending on coil)

• Internal Leakage: Less than 5 drops/min at 210 bar

• Temperature Range: $-40°C$ to $+120°C$ (with FKM seals)

Key Technical Advantages:

• Precision-Ground Spool & Sleeve: Vacuum heat-treated spools are ground to micron-level tolerances, ensuring a near-zero leakage seal even under extreme operating pressures.

• Class H Insulated Coils: Standard-equipped with Class H insulation for superior heat dissipation and high-temperature resistance. Supports 100% duty cycle, preventing burnout during prolonged operation.

• Wet-Type Armature Construction: The armature operates immersed in hydraulic oil, utilizing fluid damping to reduce noise and enhance vibration resistance—ideal for harsh mobile equipment environments.

• Modular Cartridge Design: Compatible with standard ISO/SAE cavities. Maintenance is simplified as the valve can be replaced by simply unscrewing it from the manifold without disturbing any hydraulic plumbing.

Application Areas:

• Hydraulic Power Units (HPU): Emergency shut-off or load-holding in various circuits.

• Mobile Equipment: Attachment circuit switching in excavators and safety valves for aerial platforms.

• Injection Molding: Auxiliary control for mold opening/closing circuits.

• Agriculture Machinery: Bypass circuits for harvester drum speed control systems.

Expert Maintenance Tips:

• Installation Torque: Always use a torque wrench according to specifications (e.g., 34 Nm for Size 08). Excessive torque can distort the valve sleeve, leading to spool sticking.

• Voltage Regulation: Maintain power fluctuations within $\pm 10\%$. Low voltage may prevent the pilot from opening (poor suction), while high voltage can shorten coil life.

• Fluid Cleanliness: Cartridge valves are sensitive to contamination. We recommend $10 \mu m$ filtration to maintain oil at ISO 18/16/13 or better, preventing pilot orifice clogging.
