ASCO 257 Pilot Solenoid Valve RFQ Guide
Procurement Guide / July 2026 / 6 min read / By Shengshi Engineering Team
Quick answer: ASCO 257 pilot solenoid valve RFQs should confirm the valve function, voltage, port or fitting style, enclosure requirement and dust collector pulse-valve duty before sourcing. A complete model code or nameplate photo helps avoid ordering the wrong coil or connection.
What the ASCO 257 is used for
Emerson describes the ASCO Series 257 as a 2-way normally closed direct-acting pilot valve family used with large dust collector pulse valves. For procurement, the key point is not only the series number but the exact configuration required for the installed system.
JSSS Nova keeps the related ASCO 257 product page and Solenoid Valves category connected so buyers can move from selection notes to an RFQ path.
Information to send before an RFQ
- Complete ASCO model code or clear nameplate photo
- Coil voltage and power requirement
- Port, fitting or panel-mounted configuration
- Enclosure or hazardous-area requirement if applicable
- Dust collector, pulse-valve or installed equipment details
- Quantity and required documentation
Where it fits in solenoid valve sourcing
The ASCO 257 is usually searched as a model-specific replacement or RFQ item, not as a general solenoid valve introduction. Buyers comparing options should also review the ASCO brand page, the ASCO Solenoid Valve Catalog, and the broader solenoid valve selection guide.
FAQ for ASCO 257 procurement
Can JSSS Nova quote an ASCO 257 replacement?
Yes. Send the exact model code, voltage, connection and application details so the configuration can be checked before quotation.
What should not be assumed from the series number alone?
Do not assume voltage, fitting style, enclosure or coil details from the series name alone. Confirm the installed configuration first.
What if the old nameplate is unclear?
Send photos of the valve, coil, port connection and installed equipment. The team can use those details to narrow the configuration before preparing an RFQ response.
Procurement tip: If the valve is part of a dust collector or pulse system, include equipment photos and any panel or manifold information. This makes it easier to check whether the RFQ is for the pilot valve, coil, fitting set or a complete assembly.
Need help confirming the configuration?
Send model codes, nameplate photos or process details through the RFQ form. Shengshi engineers can review the configuration and documentation requirements before quoting.
