SV4-10-C-0-24DG Eaton Cartridge Solenoid Valve 23L 210bar

Product Overview

The SV4-10-C-0-24DG, SV4-10-0-0-230AG and SV4-8-3-A2G-24DGS are Eaton/Vickers by Danfoss SV4 Series screw-in cartridge solenoid reversing valves. The SV4-10-C is a 2-way, 2-position, direct-acting, spool-type, normally closed valve rated at 23 L/min and 210 bar; the SV4-10-0 is the normally open version; the SV4-8-3 is a 3-way, 2-position direct-acting spool valve. Hardened, ground and honed working parts combined with continuous-duty coils deliver reliable bidirectional blocking or directional control. Fully interchangeable with original SV4 series cavities and electrical interfaces, every unit undergoes 100% simulated operating-condition testing for low-leakage performance in mobile and industrial hydraulic systems.

• Seals: Standard Buna-N (Viton optional)
• Recommended filtration: ISO 4406 18/16/13 or cleaner
• Installation torque (aluminum housing): approx. 47–54 Nm (SV4-10); 34–41 Nm (SV4-8)

Key Technical Advantages

1. Hardened and honed spool design: Precision-ground spool and cage minimize internal leakage for reliable bidirectional blocking or directional shifting, ideal for load-holding and safety functions.
2. Direct-acting fast response: No pilot pressure required, delivering rapid actuation, compact size and low pressure drop.
3. Full interchangeability: Exact match to Eaton/Vickers/Danfoss SV4 cavities, mounting dimensions and coil interfaces for drop-in replacement of original cartridges and coils.
4. Continuous-duty coil compatibility: Supports J/S-series continuous-rated coils with robust IP protection, vibration resistance and wide temperature capability for mobile applications.
5. 100% factory testing and long service life: Validated under simulated conditions; hardened working surfaces significantly extend operational life.

Application Areas

• Bidirectional blocking or 3-way directional control on construction and agricultural machinery
• Safety shut-off, bypass and single-acting cylinder control in industrial hydraulic systems
• Load-holding and unloading circuits on mobile equipment
• Low-leakage 2-way or 3-way direct-acting reversing functions
• OEM service and aftermarket replacement of SV4 Series cartridge solenoid valves

Expert Maintenance Tips

1. Clean the cavity and sealing surfaces thoroughly before installation; fit the correct O-rings and torque to specification (avoid over-tightening aluminum housings).
2. De-energize and depressurize before coil replacement; match voltage and connector type (DIN etc.) and keep the plug seal intact.
3. Maintain fluid cleanliness to ISO 4406 18/16/13 or better; inspect filtration regularly to prevent spool sticking.
4. Coil heating during continuous duty is normal; investigate delayed response or increased leakage by verifying voltage range and checking for spool wear.
5. On 3-way models observe port 1 pressure limits (typically ≤20–30 bar in certain configurations) to avoid damage.
