Tokyo Keiki Solenoid Valve DG4M4-34C-200AC-20-JA

Tokyo Keiki (Tokimec) DG4M4-34C-200AC-20-JA is a high-performance miniature solenoid directional valve, specifically engineered for hydraulic systems that demand compact installation space and stable, precise directional control. It adopts a resin-molded dual-frequency coil design, fully compatible with 50/60Hz power supply without rewiring, and features a wet armature structure for efficient, low-noise, and long-term reliable operation. This valve is widely used in machine tools, industrial automation lines, injection molding machines, die casting equipment, and other hydraulic circuits requiring compact and precise control.

1. Complete Model Interpretation

Model: DG4M4-34C-200AC-20-JA

  • DG4M4: Series Name – Miniature solenoid directional valve (gasket mounting, wet armature type), designed for medium and high-pressure hydraulic systems, with a compact structure that saves installation space.

  • 3: Spool Type – Spring-centered type (3-position, double solenoid), ensuring the spool automatically resets to the neutral position when the solenoid is de-energized, avoiding system misoperation and improving operational safety.

  • 4: Spool/Spring Arrangement – Special customization specification, with a tailored spool configuration to meet specific flow and directional control needs of different hydraulic circuits.

  • C: Additional Configuration – Standard configuration, compatible with common hydraulic media and general industrial installation scenarios, no additional customization required for conventional applications.

  • 200AC: Solenoid Voltage – AC 200V, dual-frequency (50/60Hz) resin-molded coil, corrosion-resistant and moisture-proof, adapting to different power supply environments without rewiring.

  • 20: Design No. – Standard design code, representing the basic structural parameters, manufacturing standards, and material specifications of the valve body.

  • JA: Special Mark – Standard product identification, indicating compliance with Tokyo Keiki’s original factory quality standards, technical specifications, and after-sales service requirements.

3. Main Functions & Characteristics

Compact & Space-Saving Design

Adopting a miniature structural design, the valve features small volume and light weight, making it ideal for hydraulic systems with limited installation space. The gasket mounting method simplifies the installation process, reduces the overall layout space of the hydraulic circuit, and facilitates later maintenance and replacement.

Stable & Efficient Operation

Equipped with a wet armature structure, it has the advantages of low energy consumption, low noise, and fast response. The resin-molded coil is corrosion-resistant, moisture-proof, and dust-proof, ensuring stable operation in harsh industrial environments (such as high humidity, dust, and temperature fluctuations). The dual-frequency coil design eliminates the need for rewiring when switching between 50Hz and 60Hz power supplies, improving the versatility and applicability of the valve.

Reliable Directional Control

The spring-centered spool design (3-position, double solenoid) ensures that the spool automatically returns to the neutral position when the solenoid is de-energized, effectively preventing misoperation of the hydraulic system and protecting the actuator and related components. The customized spool arrangement (marked with "4") can be adapted to specific directional control requirements of different hydraulic circuits, enhancing the flexibility of application.

Wide Compatibility & High Durability

Compatible with multiple hydraulic media, it can be used in various industrial scenarios. It can be perfectly matched with other Tokyo Keiki hydraulic components (such as pumps, valves, and cylinders) to form a complete and efficient hydraulic control system. The valve body is made of high-quality materials, with strong pressure resistance and wear resistance, ensuring long service life and reducing maintenance costs.

4. Typical Application Scenarios

  • Machine tool hydraulic systems: Directional control of feed mechanisms, clamping mechanisms, tool changing mechanisms, and coolant control systems.

  • Injection molding machines/die casting machines: Control of mold opening, mold closing, ejection, and material feeding mechanisms.

  • Automatic production lines: Directional control of hydraulic actuators (such as cylinders and motors) in assembly lines, conveying lines, and sorting equipment.

  • Light industrial hydraulic equipment: Compact hydraulic systems requiring precise directional control, such as small hydraulic presses, packaging machinery, and textile machinery.

5. Model Selection & Replacement Recommendations

Same Series Alternative Models (Voltage Variation)

  • DC 12V: DG4M4-34C-12DC-20-JA

  • DC 24V: DG4M4-34C-24DC-20-JA

  • AC 100V: DG4M4-34C-100AC-20-JA

Same Series Alternative Models (Spool Type Variation)

  • Spring offset A type (2-position, single solenoid): DG4M4-32A-200AC-20-JA

  • Spring offset B type (2-position, single solenoid): DG4M4-32B-200AC-20-JA

  • Standard spring-centered type (3-position, double solenoid): DG4M4-30C-200AC-20-JA

Functional Equivalence

This valve can directly replace other Tokyo Keiki DG4M4 series solenoid valves with the same installation size, pressure, and flow parameters. It is also compatible with most standard hydraulic circuits of other brands, reducing replacement costs and maintenance time.
