ASCO 320 (8320) Solenoid Valve RFQ Checklist
Procurement Guide / July 2026 / 6 min read / By Shengshi Engineering Team
Quick answer: An ASCO 320 (8320) solenoid valve RFQ should include the complete part number or nameplate, 3-way function, normal position, pipe size, voltage, AC/DC frequency, body material, seal material, coil or enclosure requirement, quantity and application medium. The 8320 family has many electrical and construction options, so a short series name is not enough for reliable sourcing.
Why ASCO 320 (8320) details matter
Emerson describes the ASCO Series 320, also known as 8320, as a general service 3-way solenoid valve family for a broad range of applications. Public ASCO datasheets show multiple choices around pipe size, operation, voltage, body material and certifications. For maintenance and procurement teams, those choices decide whether a replacement valve will match the installed pneumatic or utility circuit.
JSSS Nova supports this request path through the ASCO brand page, Solenoid Valves category, ASCO 320 (8320) product page, the related ASCO 257 RFQ guide and the RFQ form.
Information to send before asking for price
- Complete ASCO part number or clear nameplate photo from the installed valve
- Valve function: 3-way, normally closed, normally open or universal operation where specified
- Pipe size and connection standard, such as 1/8 in or 1/4 in NPT where applicable
- Voltage, AC/DC type and frequency, including 24 V, 110/120 V, 220/240 V or other project voltage
- Body material, seal material, coil type and enclosure or hazardous-area requirement
- Working medium, operating pressure, temperature and mounting environment
- Quantity, destination, urgency and whether the request is for replacement, spare stock or new equipment build
Replacement checks that reduce mismatch risk
Before replacing an ASCO 8320 valve, confirm the installed port arrangement and wiring. Two valves with similar bodies can differ by normal position, voltage, coil type or approval. If the valve is mounted inside a packaged machine, send photos of the valve body, coil label, manifold or tubing connections and the equipment nameplate.
For related procurement workflows, compare this checklist with the ASCO 257 pilot solenoid valve RFQ guide, solenoid valve selection guide, ASCO solenoid valve catalog resource and obsolete industrial spare parts guide.
FAQ for ASCO 320 (8320) sourcing
Can JSSS Nova help quote an ASCO 320 or 8320 valve?
Yes. Send the complete part number, nameplate photo, port size, voltage, valve function, body and seal material, quantity and application medium so the configuration can be checked before quotation.
Is “ASCO 8320” enough for a replacement request?
No. The series name does not define the normal position, voltage, pipe size, body material, coil option or approval. A full part number or clear photos are needed.
What should I check if the coil failed but the valve body remains installed?
Send the coil label, voltage, frequency, valve body tag and installation photo. The coil and valve body need to be matched against the installed duty and environment.
Can JSSS Nova guarantee certifications from the series datasheet?
No. Certification or approval requirements must be stated in the RFQ and checked against the exact offered configuration before order confirmation.
Procurement tip: For ASCO 320 (8320) valves, collect the full part number, normal position, pipe size, voltage, coil/enclosure requirement, body and seal material, medium, pressure, quantity and photos before requesting price.
Need help checking an ASCO 8320 request?
Send the part number, nameplate photo, voltage, function, pipe size, body and seal material, coil or enclosure requirement, medium, pressure, quantity and destination through the RFQ form. Shengshi engineers can review the details before preparing a sourcing response.
