What to specify in your RFQ

Manufacturers quote faster and more accurately when your request covers these points.

  • Size / nominal diameter

    Specify the pipe size or range of diameters (e.g., DN50 / 2" up to DN600 / 24") so the manufacturer can confirm suitable models and tooling.

  • Pressure rating / class

    Give the required pressure rating (PSI, bar or PN) so suppliers can propose appropriate body and seat designs.

  • Body / disc / seat materials

    Specify materials (cast iron, ductile iron, stainless grades, rubber seat compounds, etc.) for corrosion and media compatibility.

  • End connection type

    State whether you need wafer, lug, flanged, or Tri‑Clamp/sanitary ends so the correct body style is quoted.

  • Actuation

    Indicate manual (lever/gear) or actuator type (pneumatic, electric, hydraulic) and any mounting/torque requirements.

  • Temperature and media

    Provide operating temperature range and fluid type (water, slurry, chemical, steam) to verify seat and seal materials.

  • Standards & certifications

    List required standards (ISO, ANSI, API, CE, WRAS, etc.) and test requirements (shell/seat test, fire-safe) for compliance.

  • Quantity & delivery

    State order quantity (initial and annual) and required delivery dates to allow manufacturers to quote MOQs and lead times.

Sourcing FAQ

How do I verify a butterfly valve manufacturer?
Ask for product datasheets, factory photos or videos of manufacturing/assembly, material certificates and records of tests (shell/seat), and verify listed standards or third‑party approvals on the manufacturer's website.
What minimum order quantities (MOQs) should I expect?
MOQs vary by manufacturer and model: some makers will supply single prototype units while others have higher MOQs for custom materials or actuated assemblies. Always request MOQ when you ask for a quote.
Which certifications matter for butterfly valves?
Relevant certifications depend on application: common ones include ISO quality systems, CE/ATEX for European markets, WRAS for potable water, and industry standards such as API, ANSI or EN for dimensional and pressure ratings.
What drives lead time for butterfly valves?
Lead times depend on size/material availability, whether valves are standard or custom, actuator supply, testing requirements, and current factory workload; confirm lead time in the formal quote.
