Key Technical Advantages (M-3SED Series Common)

1. Poppet-Type Leakage-Free Design — Superior Sealing Performance

The M-3SED series features poppet-type construction, achieving metal-to-metal sealing against the seat in the closed position. Unlike spool-type valves, the poppet design delivers extremely low internal leakage in the closed state, enabling reliable switching even after long periods under pressure [1†L27-L28]. Blocked connections are leak-tight [1†L26-L27].

2. 350 bar High Pressure and 25 L/min Flow Capacity

Delivers 350 bar (5075 psi) maximum operating pressure and 25 L/min flow capacity in a compact NG6/NG10 package [0†L7][7†L8]. Suitable for diverse medium-to-high pressure hydraulic systems requiring precise directional control.

3. Wet-Type Solenoid Design for Quiet, Long-Life Operation

Features wet-pin DC solenoid design—the movable iron core operates fully submerged in hydraulic oil, providing lubrication to reduce wear and cushioning against switching impact and vibration [7†L12]. The solenoid coil is rotatable by 90° for flexible electrical connection orientation [1†L29]. Coils can be replaced without opening the pressure-tight chamber [6†L30-L32].

4. 100% Continuous Duty Rating with 150°C Temperature Resistance

Coils are rated for 100% continuous duty, with maximum coil temperature reaching 150°C [4†L37-L38]. Ensures long-term stable operation under sustained high-load conditions.

5. Concealed Manual Override for System Safety

All models feature a concealed manual override as standard [7†L7][11†L12]. In case of power failure or emergency, the valve can be manually actuated for emergency directional control, ensuring system safety.

6. Multiple Seal Options with Broad Fluid Compatibility

The M-3SED series offers NBR (standard) [10†L10] and FKM (/V suffix for heat and chemical resistance) [7†L8] seal options. Compatible with HL, HLP, HLPD, HVLP, HVLPD, HFC, and other hydraulic fluids [5†L25][10†L10-L11].

7. International Standard Compliance for Global Interchangeability

Mounting conforms to ISO 4401-03-02-0-05 (NG6) [10†L8-L9] and NFPA T3.5.1 R2 D03 [5†L16] international standards. Fully compatible with globally adopted interfaces for direct replacement of same-series, same-specification products.

Expert Maintenance Tips

1. Installation Guidelines

• M-3SED6 mounting must conform to ISO 4401-03-02-0-05 / CETOP 3 standards [10†L8-L9].

• M-3SED10 mounting must conform to corresponding NG10 standards.

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

• Tighten mounting bolts evenly to the specified torque to ensure proper sealing between the valve body and mounting surface.

2. Hydraulic Fluid Cleanliness

• Compatible fluids: HL, HLP, HLPD, HVLP, HVLPD, HFC [5†L25][10†L10-L11].

• Seal material: NBR (standard) or FKM (/V suffix) [7†L8][10†L10].

• Install a return line filter with minimum 10 μm filtration rating.

3. Electrical Connection Specifications

• All models use 24V DC supply [0†L6][7†L13].

• Voltage tolerance: ±10% [4†L37].

• Power consumption: 30 W (fixed) [4†L37].

• Electrical connector: 3-pin device plug (2 + PE) per EN 175301-803 [10†L11-L13].

• Ensure the connector is fully locked to maintain effective protection.

4. Coil Replacement Notes

• Solenoid coils can be replaced without opening the pressure-tight chamber [6†L30-L32].

• Coils are rotatable by 90° — adjust coil orientation according to wiring requirements during installation [1†L29].

• For AC voltage supply, a rectifier can be used [1†L28].

5. Manual Override

• All models feature a concealed manual override [5†L21][7†L7].

• Manual operation is for emergency use only and is not recommended for continuous duty.

6. Periodic Maintenance Inspection

• Inspect the valve body for external oil leakage every 2,000 operating hours or at least annually.

• Check electrical connectors for looseness, oxidation, or moisture ingress.

• If response lag or unstable shifting is observed, first check system fluid cleanliness and poppet seal condition.

• The M-3SED series poppet design features extremely low internal leakage—if abnormal leakage increase is observed, inspect the valve seat sealing surface for damage.
