المصادر & Inspection Notes

Verify coil voltage: 575616 is DC12V, do not confuse with DC24V model 575617

Port thread is NPT (taper thread), not G parallel thread

Used-valve inspection: energize to verify spool switching, check for internal leakage, measure coil resistance

رقم الطلب. 575616, VSNC series 3/2 normally closed solenoid valve, تيار مستمر12 فولت, NPT1/4

1. نطاق درجة الحرارة

Operating ambient temperature: -20درجه مئوية ~ +60 درجه مئوية (-10℃ … +50℃ recommended for long-term full-load coil service life)

Compressed-air medium temperature: -20درجه مئوية ~ +60 درجه مئوية

تخزين / درجة حرارة النقل: -40درجه مئوية ~ +70 درجه مئوية

Note for low-temperature service: Compressed air must be adequately dried to prevent internal icing and spool jamming.

2. حماية الدخول

IP65 rating (only valid with properly fitted and locked original DIN connector)

⚠️ Without plug fitted, IP rating is invalid. Not for splash-prone or dusty environments. Non-explosion-proof unit; must not be deployed in hazardous explosive atmospheres.

3. Medium Requirements
4. Permitted media: الهواء المضغوط, inert gas. Steam, corrosive gas or liquid media are prohibited.
5. Compressed-air quality class: ISO 8573-1:2010 [7-4-4]; minimum filtration grade 40 μm. Oil-fog lubrication optional. Once oil lubrication is applied, continuous oil supply must be maintained; switching back to oil-free operation is not allowed.
6. ضغط التشغيل: 2.5-10 bar; minimum actuation pressure 2.5 bar. Spool may fail to shift reliably below this threshold.
7. تآكل, رطوبة, اهتزاز & صدمة

CRC-2 moderate corrosion resistance: Designed for general-purpose industrial workshops. Not suitable for heavy salt-spray, strong acid/alkali, or heavy cutting-fluid splash conditions.

الرطوبة النسبية: 5-95%. Condensation permissible only if connector sealing prevents coil short-circuit from internal dew formation.

Vibration and shock: Compliant with EN60068-2 for typical industrial vibration. Avoid sustained shock above 10-20 g, which may trigger unintended switching or coil damage.

Mounting orientation: unlimited, any installation angle allowed

5. Suitable Working Conditions

✅ موصى به: General-purpose automated assembly lines, آلات التعبئة والتغليف, robotic equipment, wood-working machines, standard machine tools, indoor pneumatic manifolds, moderately dusty dry workshops.

❌ Not recommended:

Outdoor exposed installation with persistent rain exposure (IP65 is splash-resistant only, not for long-term sun/rain exposure)

Salt-spray coastal locations, electroplating workshops, heavily corrosive chemical environments

Explosion-hazard zones (no ATEX / شهادة مقاومة للانفجار)

Locations where heavy cutting fluid or oil mist directly impinges the coil assembly

6. On-Site Operational Recommendations
7. NPT tapered thread: Do not over-torque valve body during installation to avoid housing cracking.
8. DC12 V coil: Permitted supply voltage tolerance: -14% ~ +10%. Excessive deviation causes coil overheating and burnout.
9. High-humidity / large diurnal temperature swing: Apply sealant at connector interface to stop condensed moisture entering coil cavity.
10. Low-temperature installation: Fit upstream air dryer to eliminate condensate and icing risk.

وحدة: مم; valve body only, electrical plug excluded; port NPT1/4

Overall Physical Dimensions

Pneumatic Port Specification

منافذ العمل: NPT 1/4 (taper thread, not G parallel thread)

أسلوب التركيب: sub-base mounting, bottom-entry manifold ports.

Sub-Base Mounting Hole Layout (valve bottom face)

1. Fastener: M5 clearance holes
2. Center-to-center distance between mounting holes: 44 mm
3. Edge clearance from mounting hole to valve side face: 8 mm

Compatible with standard VSNC sub-bases and manifold plates.

MZD-D12 DC12V Coil Dimensions

Coil width: 32 mm

Coil thickness: 24 mm

Electrical interface: Standard DIN43650 Form-A plug. Plug protrudes approx.13 mm outward; reserve clearance in cabinet layout.

Layout Clearance Reference

Without plug fitted: 112(ل) × 32(دبليو) × 58(ح)

With standard plug fitted: add 13 mm along length axis → total length ≈125 mm

Important Reminders

1. Do not force NPT taper thread into G-thread base, thread damage will occur.
2. Manifold stacking: each valve occupies fixed 32 mm width.
3. I can supply dimension-annotated drawing notes for CAD, or HS-code information upon request.

Order No.575616; 3/2 نورث كارولاينا, NPT1/4, sub-base-mounted, DC12 V coil

⚠️ Common online-source error: Do not confuse VSNC (32 mm width 3/2 صمام) with high-flow VUVS series (2000 l/min); parameters are not interchangeable.

Practical Flow Estimation

1. Supply pressure 6 bar(ز), downstream load pressure 5 bar: practical output ~640-680 l/min
2. Supply pressure 8 bar(ز), downstream load pressure 6 bar: practical output ~780-820 l/min

إرشادات التطبيق

1. 3/2-way valves are intended for single-acting cylinders, blow-off and vent circuits. Not suitable for driving large-bore double-acting cylinders.
2. If flow 900 l/min is required, upgrade to VUVS series.
3. For NPT1/4 port, max recommended tubing OD is 12 mm. Excess pipe length will further reduce actual flow capacity.
