Soft spool design: Low wear, excellent sealing.
Coil IP65, 過酷な産業環境に適しています.
RoHS compliant for global markets.
- インストール & メンテナンス
Installation Rules
- Mount the valve vertically upward, with the arrow matching airflow direction.
- Clean piping before connection; install a filter (≥40 μm).
- Ensure voltage variation within ±10% of rated to avoid coil burnout.
- Tightening torque for Rc1/8: 10–12 N·m to prevent leakage.
メンテナンスガイド

一般的な障害 & On‑Site Solutions (Quick Repair)
- No Operation When Powered
- No power / wrong voltage
原因: 配線の緩み, broken wire, mismatched voltage (AC/DC confusion, 低電圧)
修理: Measure voltage → verify DC24V/AC220V → retighten wiring.
- Coil burned / 開回路
原因: 過電圧, water ingress, insulation aging.
修理: Test coil with multimeter → replace with same‑spec coil.
- Pilot air passage blocked
原因: Contamination in air lines.
修理: Remove pilot head → clean pilot orifice → dry and reassemble.
- Air pressure too low
原因: Below minimum 0.2 MPa.
修理: Increase supply pressure to 0.2–0.7 MPa.
- Slow, Sticky or Delayed Switching
- Insufficient pressure / low flow
修理: Check regulator, pipe diameter, filter clogging.
- Contamination or poor lubrication on spool / sleeve
修理: Disassemble → clean spool → apply small amount of silicone grease → reassemble.
- Fatigued or deformed spring
修理: Replace return spring assembly.
- Air Leakage (External / Internal)
External Leakage (Ports / Body)
- Poor thread sealing
修理: Rewrap with Teflon tape / apply sealant, torque 10–12 N·m.
- Worn or damaged O‑rings
修理: Replace O‑rings / gaskets.
Internal Leakage (Continuous exhaust port leakage, cross‑talk)
- Worn or scratched spool seals
修理: Clean or replace spool and sleeve assembly.
- Contamination trapped on sealing surfaces
修理: Disassemble and clean; install 40 μm filter upstream.
- No Switching / No Reset After Power Off
- Fails to reset when de‑energized
原因: Broken spring, 変形, spool sticking.
修理: Replace spring → clean spool → remove contaminants.
- No switching when energized
原因: Weak coil, blocked pilot air, seized spool.
修理: Replace coil → restore pilot air → clean valve body.
- コイル過熱 / Burnout
- Voltage fluctuation beyond ±10%
修理: Stabilize power supply, add regulator/filter.
- Coil water ingress / moisture
修理: Use waterproof connectors and sleeves, maintain IP65 environment.
- Continuous energization with poor ventilation
修理: 換気を改善する; use low‑power R‑series coil.
- Loud Exhaust Noise / 異音
- No muffler on central exhaust
修理: Install miniature muffler.
- Exhaust restriction or airflow impact
修理: Clean clogged muffler → check for kinked exhaust tubing.
Quick Preventive Maintenance (for customers)
- Air supply must be filtered + dried to prevent water, 油, and dust.
- Clean or replace mufflers regularly.
- Keep voltage stable to avoid coil overheating.
- Prepare spares: coils, O‑rings, spring kits.
