4GD210-06-C-3-CKD Technical Specifications & Application Guide

This is a pilot‑operated 5/2‑way solenoid valve manufactured by CKD (ญี่ปุ่น), a basic pneumatic control component in the 4GD series, commonly used for controlling pneumatic actuators in automated production lines.

Port size: Rc1/8 (06), direct piping type, single‑solenoid 2/5‑way, central exhaust design.

Standard voltage: typically DC24V.

Can be upgraded to the new‑generation 4GD/E R Series and is compatible with same‑size models such as 4GA210.

1. Model Explanation

2. Core Specifications

3. คุณสมบัติ
4. Structural Advantages

Pilot‑operated: Main valve controlled by small pilot valve, low electromagnetic force required, suitable for high flow.

Direct piping: Simplifies installation, reduces leakage points, ideal for limited spaces.

Central exhaust: Concentrated exhaust, low noise, simplified piping.

2. Control Characteristics

Single solenoid + spring return: Automatically resets when power is off, improves safety.

2/5‑way: Controls cylinder reciprocation, suitable for most pneumatic actuators.

Interchangeable with 4GA/4GB series in the same size, improving versatility.

3. ความน่าเชื่อถือ

Soft spool design: Low wear, excellent sealing.

Coil IP65, suitable for harsh industrial environments.

RoHS compliant for global markets.

4. การติดตั้ง & Maintenance

Installation Rules

1. Mount the valve vertically upward, with the arrow matching airflow direction.
2. Clean piping before connection; install a filter (≥40 μm).
3. Ensure voltage variation within ±10% of rated to avoid coil burnout.
4. Tightening torque for Rc1/8: 10–12 N·m to prevent leakage.

Maintenance Guide

การแก้ไขปัญหา

1. No operation: Check power → pressure ≥0.2 MPa → coil burnout → pilot orifice blockage.
2. Leakage: Check port seals → spool seals → valve body cracks → exhaust dust.
3. Slow response: Check pressure → pipe diameter → spool sticking.
4. อัพเกรด & Replacement
5. Same‑brand Upgrade

Recommended upgrade: 4GD210R-06-C-3 (4GD/E R Series)

ข้อดี:

Power consumption reduced to 0.1 ว (low heat), energy saving.

15% faster response.

Connectors can be mounted upward/sideways.

Optional exhaust anti‑malfunction valve for higher safety.

ความเข้ากันได้: Identical mounting dimensions, direct replacement.

2. Same‑size Alternatives

4GA210-06-3: Manifold type, same ports and dimensions, only piping differs.

4GD219R-06-C-3: Upgraded version with optimized sealing.

3. Cross‑brand Alternatives

6. Applications
7. Automated lines: Pneumatic grippers, small cylinders, electronics & automotive assembly.
8. Packaging machinery: Actuator positioning, material feeding.
9. เครื่องจักรสิ่งทอ: Pneumatic tension control, yarn guide positioning.
10. Medical equipment: Precision pneumatic control, clean environments.
11. Purchasing & Selection Tips
12. Confirm voltage (DC24V/AC220V), piping type (direct/manifold), exhaust (central/individual).
13. New projects: recommend 4GD/E R Series; retrofits: direct replacement.
14. Spare parts: stock 10% of usage to reduce downtime.
15. Authenticity: Purchase via authorized CKD distributors for quality and service.

Common Faults & On‑Site Solutions (Quick Repair)

1. No Operation When Powered
2. No power / wrong voltage

Cause: สายไฟหลวม, broken wire, mismatched voltage (AC/DC confusion, low voltage)

Fix: Measure voltage → verify DC24V/AC220V → retighten wiring.

2. Coil burned / วงจรเปิด

Cause: แรงดันไฟฟ้าเกิน, water ingress, insulation aging.

Fix: Test coil with multimeter → replace with same‑spec coil.

3. Pilot air passage blocked

Cause: Contamination in air lines.

Fix: Remove pilot head → clean pilot orifice → dry and reassemble.

4. Air pressure too low

Cause: Below minimum 0.2 MPa.

Fix: Increase supply pressure to 0.2–0.7 MPa.

2. Slow, Sticky or Delayed Switching
3. Insufficient pressure / low flow

Fix: Check regulator, pipe diameter, filter clogging.

2. Contamination or poor lubrication on spool / sleeve

Fix: Disassemble → clean spool → apply small amount of silicone grease → reassemble.

3. Fatigued or deformed spring

Fix: Replace return spring assembly.

3. Air Leakage (External / Internal)

External Leakage (Ports / Body)

1. Poor thread sealing

Fix: Rewrap with Teflon tape / apply sealant, torque 10–12 N·m.

2. Worn or damaged O‑rings

Fix: Replace O‑rings / gaskets.

Internal Leakage (Continuous exhaust port leakage, cross‑talk)

1. Worn or scratched spool seals

Fix: Clean or replace spool and sleeve assembly.

2. Contamination trapped on sealing surfaces

Fix: Disassemble and clean; install 40 μm filter upstream.

4. No Switching / No Reset After Power Off
5. Fails to reset when de‑energized

Cause: Broken spring, deformation, spool sticking.

Fix: Replace spring → clean spool → remove contaminants.

2. No switching when energized

Cause: Weak coil, blocked pilot air, seized spool.

Fix: Replace coil → restore pilot air → clean valve body.

5. Coil Overheating / Burnout
6. Voltage fluctuation beyond ±10%

Fix: Stabilize power supply, add regulator/filter.

2. Coil water ingress / moisture

Fix: Use waterproof connectors and sleeves, maintain IP65 environment.

3. Continuous energization with poor ventilation

Fix: Improve ventilation; use low‑power R‑series coil.

6. Loud Exhaust Noise / Abnormal Sound
7. No muffler on central exhaust

Fix: Install miniature muffler.

2. Exhaust restriction or airflow impact

Fix: Clean clogged muffler → check for kinked exhaust tubing.

Quick Preventive Maintenance (for customers)

1. Air supply must be filtered + dried to prevent water, oil, และฝุ่น.
2. Clean or replace mufflers regularly.
3. Keep voltage stable to avoid coil overheating.
4. Prepare spares: coils, O‑rings, spring kits.
