8. 선택 지침 & Replacement Rules

선택 팁

Three key factors for SY3220 selection: 전압, wiring and port size;

5 stands for 24V, G for direct wire outlet;

C4 for Φ4 tube, C6 for Φ6 tube;

20 for single-coil, 40 for dual-coil match;

10mm miniature body, manifold mounting saves space.

Selection Decision Tree

1. 제어 전압: 선택하다 5 for DC24V, 4 for AC110V, 6 for AC220V
2. 배선 유형: Fixed installation → G (direct outlet); Frequent replacement → LZ/LD (socket type)
3. 포트 크기: Low flow → C4 (Φ4mm); High flow → C6 (Φ6mm)
4. 제어 모드: Single-acting → 20 single-coil; Double-acting → 40 dual-coil
5. 설치: Manifold mounting → Standard type; Independent mounting → Model with F1 bracket

교체 권장사항

Budget limited: Choose Airtac 4V210-06, 30% cost down, sufficient performance for most working conditions

Frequent maintenance: Select LZ/LD socket type for fast coil replacement and less downtime

Higher flow required: Upgrade to SY5220 series (medium body, effective area 2.8mm²)

가혹한 환경: Choose UE suffix model (표시기 포함 + surge protection) for higher reliability

9. 일반적인 응용 분야
10. 전자 장비: Small cylinder drive, automatic assembly line, PCB conveying & 포지셔닝
11. 포장기계: Label attaching, film tension control, packaging sealing cylinder
12. 의료 장비: Pneumatic control of analytical instruments, sample conveying mechanism
13. Automation Production Line: Jig & fixture positioning, small manipulator joint control
14. Food Processing: Small pneumatic actuator, sorting mechanism control
15. Key Operation & 유지보수 포인트
16. Before Installation: Ensure medium cleanliness (5μm filter recommended) to prevent seal damage by impurities
17. Installation Direction: Follow the flow arrow on valve body; reverse installation is prohibited
18. Manifold Mounting: Use sealing gasket, tighten screws evenly (torque 0.5～0.7N·m)
19. 유지보수 주기: Inspect seals every 6 개월; replace O-rings annually
20. 문제 해결: No action → Check in sequence: Voltage → Air pressure → Coil → Pilot valve

5. Selection Mnemonic

Five key points for SY selection: 시리즈, 기능, 전압;

3=Mini,5=Medium,7=Large,9=Extra Large;

2=5/2-way,3=5/3-way remember clearly;

20=Single-coil,40=Dual-coil;

30=Closed,31=Exhaust,32=Pressure center;

5=24V,G=direct wire outlet;

C4 for Φ4,C6 for Φ6 tube;

Manifold mounting saves space, add F1 for standalone installation;

Add -Q for CE, add -P for external pilot.
