Shunfa 4V210-08 pneumatic valve
A coil-operated valve pictured in Shunfa’s 4V catalogue. The visible model and pressure identify an example; electrical options, dimensions and performance need a current configuration sheet.
One heading does not identify one valve
The selected entry is 87, not the manual-control image in entry 94.
The original photograph shows 4V210-08, a single coil/connector assembly and a body label marked 0.15–0.8 MPa. A and B appear on one face; R, P and S on the other. [1] These are catalogue-image observations, not measurements of a delivered unit.
Use this identifier
State “Shunfa 4V210-08, entry 87,” with the original URL. Request a complete offered order designation and a current datasheet.
Resolve this ambiguity
Entry 94 has the same 4V-series heading, but shows 4R210-08 with a manual control. [2] It does not establish equivalent actuation or configuration.
The pictured pressure range converts arithmetically to 1.5–8 bar. It is not a proof/burst rating, independently verified current production limit or a permissible setting for a machine. Confirm working and control-air conditions on the actual offered sheet.
Confirm behaviour before matching the housing
The photo is not a complete circuit specification.
Request the pneumatic symbol, positions, pilot arrangement and return method. Festo explains that 5/2 and 5/3 notation describes ports and positions, and that stable switching behaviour depends on the arrangement rather than just coil count. [3] This explanation does not establish compatibility with any Festo valve.
| State | Question to resolve |
|---|---|
| Command applied | Which ports connect and which exhaust? Match the offered symbol to the required actuator motion. |
| Command removed | What returns or retains the spool, and what happens to the actuator? Obtain the reset description. |
| Supply lost / restored | What control pressure is needed and what happens on restart? The body range does not define a safe state. |
| Maintenance | Define isolation and stored-energy control in the equipment procedure. A manual override is not automatically an isolator. |
No reviewed source makes this a safety-rated dump valve, load-holding device or emergency-stop system. Component approval does not approve the machine’s behaviour.
Buy the coil and connector as a defined combination
No particular voltage is established by the photograph.
Electrical supply
Specify AC/DC and nominal voltage. Request permissible voltage range, consumption, energisation duty and switching requirements. Check the control output against that coil’s electrical sheet.
Connector package
Identify connector, wiring diagram, cable entry, seals, earthing where applicable and any indicator/suppression circuit. A transparent housing does not establish polarity, pin assignment, IP protection or outdoor suitability.
Record valve and coil codes separately in the quote and sample record. Confirm whether the connector is included. Any proposed coil substitution needs a revised sheet and buyer approval.
Review the installation on a dimensioned drawing
No verified thread size or mounting footprint is supplied by this entry.
- Air connections: obtain full thread designation and sealing method for every port. Do not infer G1/4 or NPT from “08” without documentation.
- Mounting: request envelope, holes and permitted orientation. Include connector removal, cable bend and access space.
- Flow: define actuator/cycle demand and request the rated flow with reference conditions. Port appearance does not prove capacity.
- Environment: state temperature, dust/water exposure, vibration and air treatment. Obtain applicable limits rather than assigning a construction-machine rating.
- Accessories: distinguish body, coil, connector, fittings, silencers, base and hardware. Universal manifold compatibility is not established.
For replacement, retain the installed valve’s own label and symbol, and identify all interfaces being retained. A shared model code across suppliers is not a cross-brand interchangeability test.
Approve one traceable sample configuration
Appearance alone cannot close the specification gaps.
- Before manufacture: approve body/coil/connector identifiers, circuit symbol, drawing and applicable electrical/pneumatic sheets under one revision.
- Before installation: match delivered labels and components to the order. Obtain agreed inspection records; no measured switching, leakage or endurance results were supplied by the reviewed entry.
- Controlled trial: responsible personnel should use an approved procedure and conditions. Link the acceptance decision to the exact sample.
- Repeat purchase: preserve the accepted configuration and require change notification. Agree handling of wrong components, nonconformities and replacements.
Stock, lead time, price, quantity, warranty and delivery terms need a quotation. This is an CivilEquip source-based procurement review, not a claim that CivilEquip tested a valve or inspected the factory.
