Key Technical Advantages (KSO-G02 Series Common)
1. High-Pressure High-Flow Performance
The KSO-G02 series delivers an exceptional combination of 35 MPa (350 kgf/cm²) operating pressure and 100 L/min flow capacity. This performance places it at the forefront of NG6 size solenoid directional valves, making it suitable for demanding high-pressure, high-flow hydraulic systems.
2. Rugged Environmental Protection
Designed to IEC Pub529 IP65 dust and water-proof standards, the valve features effective protection against dust ingress and water jets from any direction. CE compliance makes it suitable for export to European markets and equipment requiring CE certification.
3. High-Reliability Solenoid System
The solenoid coil utilizes Class F insulation material for excellent heat resistance. Under DC24V supply, holding current is 1.22 A with holding power of 29.2 W. The valve accommodates 90–110% voltage fluctuation. Insulation resistance exceeds 50 MΩ with dielectric strength of AC1500V for 1 minute. The solenoid supports continuous duty rating.
4. Precision Machining and Long Service Life
The valve body is manufactured from high-strength cast iron, with spool and bore surfaces precision-ground to ensure minimal internal leakage and long-term shifting accuracy. With a maximum shifting frequency of 240 cycles/min, the valve is ideal for high-cycle applications. The highly reliable KSO-G02 pilot valve ensures long service life and stable operation.
5. Modular Stack Valve Compatibility
The KSO-G02 series supports modular stack valve configurations. Allows flexible integration of throttle valves, check valves, pressure reducing valves, and other hydraulic components—significantly simplifying hydraulic system layout and reducing leakage risk. G02 size uses M5 mounting bolts.
6. Flexible Spool Functions and Electrical Options
The KSO-G02 series offers a wide range of spool configurations—2-way 2-position (2B8), 4-way 2-position spring offset (2BP), 4-way 3-position spring centered (4CP), and more. Supports multiple voltage options including AC100V, AC200V, and DC24V. Terminal box type with indicator lamp enables quick field status checks.

Expert Maintenance Tips
1. Installation Guidelines
G02 size mounting surface must conform to ISO 4401-03 / CETOP 3 / NG6 standards.
Use M5 mounting bolts.
Thoroughly clean the mounting surface and all ports (P, A, B, T) before installation to prevent foreign particles from entering and causing spool sticking or seal damage.
KSO-G02 series supports modular stack valve configurations—pay attention to sealing and bolt length between stacked valve layers.
2. Hydraulic Fluid Cleanliness
Recommended fluid: Petroleum-based hydraulic oil.
Note: Certain spool types (5C/66C/51C) have maximum operating pressure of 25 MPa (250 kgf/cm²) , not 35 MPa.
Install a return line filter with minimum 25 μm filtration rating upstream of the valve.
3. Electrical Connection Specifications
KSO-G02-2BP-30-E-2T uses DC24V supply, with permissible voltage fluctuation of 90–110%.
KSO-G02-4CP-30-N uses AC100V (50/60Hz) supply.
KSO-G02-2B8-30 uses AC200V (50/60Hz) supply.
KSO-G02-2BP-30-E-2T features terminal box wiring with indicator lamp. Pay attention to indicator light connections during wiring.
Ensure the terminal box cover is properly sealed to maintain IP65 protection.
4. Back Pressure Control
G02 size system return line back pressure must not exceed 17.5 MPa (175 kgf/cm²) .
If back pressure is excessive, consider using a dedicated return line or routing the valve return port directly to the tank.
5. Periodic Maintenance Inspection
Inspect the valve body for external oil leakage every 2,000 operating hours or at least annually.
Check terminal boxes for looseness, oxidation, or moisture ingress.
If response lag or unstable shifting is observed, first check system fluid cleanliness and verify the spool is not sticking.
Indicator lamps help quickly verify solenoid energization status.
