III. 6SV210-08 VS 4V210-08 Comparison
| Article | 6SV210‑08 (Nouvelle génération) | 4V210‑08 (Legacy Classic) |
| Pilot exhaust | Internal exhaust, pilot air discharged through main R/S ports; no vent hole on coil housing, superior dust resistance | External exhaust; pilot air vents via small holes on coil housing, prone to dust ingress |
| Consommation d'énergie | 1.2W @ DC24V | 2.8W @ DC24V |
| Débit | 1080 L/min | 850 L/min |
| Electrical options | Plug-in / Cable‑out / DEPUIS / M8 (4 types) | Plug-in, DEPUIS (2 types) |
| Valve island footprint | Valve island assembly approx. 32% plus petit | Larger overall dimension |
| Interchangeabilité | Mounting hole pattern NOT compatible with 4V210‑08; cannot fit 4V‑series manifold; dedicated 6SV200M sub‑base required | For 4V‑200 series manifold bases |
⚠️Selection pitfall: Not a direct drop-in replacement for 4V210-08. For valve-island retrofitting, use only 6SV200M manifold. Tube fittings remain interchangeable for standalone body-ported installation.
- Port Identification & Commande manuelle
P.: Compressed air supply; A/B: Cylinder ports; R., S: Exhaust ports. Mufflers or exhaust throttles must be fitted.
Side-mounted manual override: Non-locking momentary push-button. Press to shift, release for reset. Used for pre-wiring manual cylinder test; do NOT hold continuously.
- Règles d'installation & Hard Restrictions (Red Lines)
- Do not drop, strike or impact the pilot coil head. Pilot assembly is precision-built; impact causes spool sticking and internal leakage.
- Coil fastening screw M2.5 torque: 0.4-0.45 N·m. Avoid over-torque to prevent thread stripping.
- Compressed-air filtration is mandatory. Heavy moisture/oil contamination drastically shortens seal service life. Use only dry compressed air as working medium.
- Single-solenoid type: Spring-reset on de-energization. Avoid continuous coil energization, which accelerates coil aging.
- Avoid heavy EMI and heavy-dust environments. Even with internal pilot exhaust, mufflers are still recommended on exhaust ports.
- Dépannage typique
| Symptôme | Cause première | Remède |
| No shifting upon energization | Mismatched coil voltage; burnt‑out coil; clogged pilot orifice; supply pressure below 0.15 MPa | Verify coil voltage; measure coil resistance; check air supply; clear pilot passage |
| Fail to reset after de‑energization | Spring jam; debris‑stuck spool; overpressure | Disassemble & clean spool; verify operating pressure; improve air filtration |
| Persistent leakage at A/B ports | Worn spool seals; particulate contamination trapped inside valve cavity | Clean or replace valve assembly |
| Excessive coil heating | Over‑voltage; continuous long‑duration energization; wrong coil specification | Duty‑cycle control; verify supply voltage |
VII. Scénarios d'application typiques
Automation assembly lines, machines d'emballage, auxiliary pneumatic circuits for injection-molding machines, machine-tool pneumatic clamps, conveyor-line cylinder control. Ideal for valve-island cluster applications requiring low power consumption, high dust resistance and enhanced flow performance.

| Spool / Sleeve | Hardened aluminum alloy, precision‑honed bore for low friction |
| Scellés (Joints toriques, spool seals) | NBR nitrile butadiene rubber, optimized for compressed‑air service; operating range ‑5~+50℃, lubrication‑free |
| Return spring | Stainless spring steel |
| Pilot housing | Flame‑retardant PA engineering plastic |
| Coil winding | Enameled copper wire; coil housing: black flame‑retardant plastic with epoxy potting sealing |
| Thread ports | Integral machined aluminum PT1/4 threads on valve body |

Notes complémentaires
- Medium limitation: Designed exclusively for dry compressed air. Not suitable for water, steam or highly corrosive gas. NBR is incompatible with ketones and ester-based organic solvents.
- Matching 6SV200M manifold sub-base: Extruded aluminum alloy + NBR gasket.
- Comparison vs legacy 4V210-08: Both use aluminum valve bodies. The 6SV series adopts optimized extrusion process for larger flow area, plus redesigned pilot housing to realize internal pilot exhaust.
AIRTAC Mainstream Solenoid Valve List & Référence équivalente multimarque
⚠️Important notice: This is functional-equivalent reference only, NOT physical drop-in replacement. Thread size, mounting footprint, manifold compatibility, coil power and Cv flow must be double-checked. Imported and domestic valve manifolds are mostly non-interchangeable; only working conditions are matched.

III. Critical Replacement Risk Notes (Selection Pitfalls)
- 6SV cannot directly reuse 4V-series manifold bases. 6SV uses internal pilot exhaust; dedicated `6SV200M` manifold required. Legacy 4V uses `4VM` manifold. Mismatched mounting hole pattern causes air leakage if forced assembly.
- Internal-exhaust vs external-exhaust:
4V: External pilot exhaust. Vent openings on coil housing; higher risk of spool jamming in dusty environments.
6SV /5V: Internal pilot exhaust. Pilot waste air discharged via main R/S exhaust ports; no vent openings on coil, better for heavy-dust equipment.
- Consommation électrique de la bobine:
Legacy 4V DC24V ≈2.8W; 6SV DC24V only 1.2W. PLC output drive capacity must be recalculated for large-scale valve islands.
- Physical mounting: SMC SY-series and FESTO VUVG valve islands feature completely different mounting footprints from AIRTAC. Cannot mix-mount on one shared manifold. Replace the whole manifold assembly for functional migration.
- 5/3-vanne de voie: Maintain identical center-position function during replacement (C=Closed-center; E=Exhaust-center; P=Pressure-center). Mismatched center function will lead to abnormal machine motion logic.
