2. Product Overview
TheDSG-01-3C2-D24-N1-50His a high-performance electromagnetic directional control valve manufactured by leading suppliers (Taiwan/Japan/Europe, depending on brand). It is designed to regulate hydraulic fluid flow in systems, enabling start, stop, and directional control of actuators (e.g., hydraulic cylinders, motors). Key features include:
• 3-Position, 4-Way Design: Provides C2-type center function (pressure-sealed) for pressure holding or locking in hydraulic circuits.
• Dual Operation: Supports remote electromagnetic control and local manual override for emergency use.
• Precision Machining: Spool-to-bore clearance ≤0.005mm ensures low leakage and extended service life.
• Environmental Robustness: Operates in temperatures from -20°C to +80°C with IP65 protection (dust/water-resistant).

4. Spool Function (C2-Type Center)
Center Position (C2-Type):

• T Port to Tank: Return port (T) directly connected to tank for reduced backpressure.
Applications:
• Hydraulic cylinder pressure holding (e.g., clamping fixtures).
• Motor braking (prevents inertial sliding).
• Sequential operation in multi-actuator circuits.
5. Typical Applications
Industrial Hydraulics
• Injection Molding Machines: Controls mold opening/closing and ejection.
• Die-Casting Machines: Manages clamping and injection cylinder movements.
• Press Brakes: Controls slide ram motion.
Construction Machinery
• Cranes: Controls luffing, slewing, and telescoping motions.
• Excavators: Manages boom, arm, and bucket cylinder operations.
Automation Equipment
• Robotics: Controls multi-axis gripping mechanisms.
• Packaging Machines: Synchronizes pneumatic/hydraulic cylinder actions.
6. Selection Guide
Step 1: Determine Port Size & Flow
• Match actuator flow requirements:
• NG6 (6mm): ≤30 L/min
• NG10 (10mm): ≤60 L/min
• NG16 (16mm): ≤120 L/min
Step 2: Choose Center Function
• Pressure Holding: Select C2-type (blocked).
• Unloading: Select H-type (P→T connected).
• Differential Connection: Select P-type (A/B interconnected).
Step 3: Confirm Electrical Specs
• Voltage Compatibility: DC 24V (industrial) or AC 110V/220V (fixed installations).
• Protection Rating: IP65 (general) or IP67 (submersible/car wash).
Step 4: Special Requirements
• Manual Override: Select 50H (emergency use).
• Explosion-Proof: Select Ex d IIC T4 (mining/chemical applications).
7. Installation & Maintenance
Installation Guidelines
1. Orientation: Install solenoid upright to prevent contaminant ingress.
2. Base Mounting: Ensure O-ring integrity between valve and subplate; torque to 25–30 N·m.
3. Electrical Wiring: Use shielded cables (≤5m length) to minimize interference.
4. System Flushing: Pre-flush piping with 10μm filters to avoid spool sticking.
Routine Maintenance
• Monthly Checks:
• Solenoid coil resistance (≈16Ω ±10% at DC 24V).
• Manual override lever flexibility.
• Annual Replacements:
• Seals (if leakage exceeds limits).
• Filters (maintain oil cleanliness to NAS 6).
Troubleshooting
【表格】
Symptom Possible Cause Solution
No Shifting Solenoid de-energized, coil burnt, spool jammed Check power, replace coil, clean valve
Slow Shifting Low voltage, spring fatigue, high oil viscosity Adjust voltage, replace spring, use lower-viscosity oil
High Internal Leakage Worn seals, spool wear, contamination Replace seals, lap spool, flush system
