KSO-G02-2BP-30-E-2T | DAIKIN Solenoid Valve 35MPa 100L/min IP65

Product Overview

The KSO-G02-2BP-30-E-2T is a direct-operated solenoid directional control valve from DAIKIN’s KSO series, conforming to Cetop3 (NG6) specifications. This series achieves an exceptional combination of 35 MPa (350 kgf/cm²) high-pressure operation and 100 L/min high-flow capacity (G02 size). Constructed from high-strength cast iron, the valve body delivers superior rigidity and fatigue resistance. Designed to IEC Pub529 IP65 dust and water-proof standards and compliant with European CE safety regulations, this valve is suitable for demanding industrial environments worldwide.

As an original DAIKIN KSO series hydraulic solenoid valve, this product offers complete interchangeability with any KSO-G02 size valve in the series, requiring no modifications to mounting interfaces or piping layouts.

Key Technical Advantages

1. High-Pressure High-Flow Performance
The KSO-G02 series delivers an exceptional combination of 35 MPa operating pressure and 100 L/min flow capacity, positioning it at the forefront of Cetop3/NG6 class solenoid valves. This performance enables directional control in high-pressure hydraulic systems without upgrading to larger valve sizes.

2. Rugged Environmental Protection
Designed to IEC Pub529 IP65 standards, the valve features dust-tight construction and protection against 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 H insulation material for excellent heat resistance. Under DC24V supply (E voltage code), holding current is only 1.25A with 30W holding power, and the valve accommodates 90–110% voltage fluctuation. 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.

5. Flexible Installation Options
Multiple solenoid connection configurations are available (terminal box type, direct lead type, etc.), with optional indicator lamps. The design prioritizes installation convenience and maintenance visibility across diverse operating conditions.

Expert Maintenance Tips

1. Installation Guidelines

• The mounting surface must conform to Cetop3 (NG6) international standards, using 4 M5×45 mounting bolts. Recommended tightening torque: 6.5–8.5 N·m (65–85 kgf·cm).

• Thoroughly clean the mounting surface and ports before installation to prevent foreign particles from entering the valve and causing spool sticking or seal damage.

2. Hydraulic Fluid Cleanliness

• Recommended cleanliness level: NAS 1638 Class 9 or ISO 4406 18/15 or better.

• Install a return line filter with minimum 25μm filtration rating upstream of the valve.

3. Electrical Connection Specifications

• For DC24V supply, ensure voltage fluctuation remains within 90–110% of rated value (21.6V–26.4V).

• Solenoid coil polarity is not specified, but follow standard wiring diagrams to ensure proper indicator lamp function.

4. Back Pressure Control

• 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 solenoid coil insulation resistance (should be ≥50 MΩ) every 2,000 operating hours or at least annually.

• Check for external oil leakage and inspect terminal connections for looseness or oxidation.
