OEM engineering brief
Application Engineering Guide
On a 4V210, ISO or NAMUR valve the real question is: will this coil drop in, run 100% ED, and not burn out on the island? The seven-point checklist below is what we use before we quote.
What the coil has to match
- MechanicalTube diameter (bore), magnetic length, mounting pitch, plug-in vs flying lead.
- ConnectorDIN 43650 Form A / B / C. A Form B coil on a Form A housing will not seal or will not fit.
- ElectricalDC 12/24 V or AC 24/110/220 V. AC and DC windings are not interchangeable on the same tube.
- DutyIslands are often 100% ED. An intermittent coil left on continuously needs more copper, not “the same 24 V.”
Drop-in checklist
If any line differs from the installed coil, it is not a drop-in. We will say so instead of shipping a look-alike.
- Bore / tube diameter and coil height.
- Voltage and AC vs DC.
- Resistance or power at 20°C — not only nominal voltage.
- Duty cycle and ambient next to the manifold (enclosure air).
- Connector form, gasket and cable gland.
- Insulation class (F/H) and heat coming from the valve body.
- Whether the valve still shifts at hot resistance / low voltage.
12 V vs 24 V
24 V DC is the default for new islands. 12 V still appears on mobile plant. Do not “standardize” by changing only the coil voltage on a valve magnetically designed around another ampere-turn number — hot force will move.
Why coils burn or fail to shift
- Island ambientPacked manifolds run 15–30°C above room. Class B dies; Class F/H survives.
- Wrong EDA 50% coil left at 100% ED.
- AC on DC or the reverseOverheating or no shift.
- DIN gasketOmitted or over-torqued, then pin corrosion.
OEM / ODM path
- Tube drawing — bore, height, voltage, DIN form, duty, volume.
- Wind spec — 100% ED and insulation class set from island ambient, not the aisle.
- Sample — typically 5–7 working days.
- Pilot — same process as mass production.
FAQ
Can I replace only the coil on a 4V210?
Yes, if bore, height, voltage, power and connector match. Measure the tube; do not order by the valve series name alone.
Form A vs Form B?
Different pin spacing and gasket. Match the connector already on the cable, or change both sides.
Will a 6 W coil shift a valve that used 3.5 VA?
Maybe, but it will run hotter. Tell us the original resistance and whether the valve is direct or pilot.
Do you have a catalogue 24 V DIN coil?
Yes. If the tube is non-standard, send the outline — faster than trying three “close” SKUs.
Send tube outline, voltage, AC/DC, duty, DIN form and volume to cici@solenoidcn.com. Hardware: coil series.
Have a drawing or sample?
Send voltage, media, pressure, duty and annual volume. We reply with a DFM note, not a catalogue dump.
