What to specify in your RFQ

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

  • Nominal size

    Specify DN150 explicitly so manufacturers quote the correct body, disc and actuator interface.

  • Pressure class / rating

    State required PN or Class (e.g., PN6/10/16, CL150) and maximum operating pressure.

  • End connection type

    Wafer, lug, flanged (specify flange standard and drill pattern) affects body design and cost.

  • Seat and disc materials

    Specify elastomer seat (EPDM, NBR, Viton/PTFE) or metal seat and disc material (stainless grades) for media compatibility.

  • Operating temperature range

    Provide min/max fluid temperature so manufacturers can recommend seat materials and coatings.

  • Actuation

    Specify manual (lever/gear) or actuator type (electric/pneumatic), mounting and control signal requirements.

  • Standards & testing

    List required standards (EN 593, API609, AWWA C504) and tests (hydrostatic, seat leakage class).

  • Quantity and delivery

    State required unit quantity and target lead time to obtain MOQ and production scheduling information.

Sourcing FAQ

How do I verify an Italian supplier actually manufactures DN150 butterfly valves?
Ask for a product datasheet or catalogue showing DN150 in the range, photos of the production site or factory, and serial-numbered test reports (hydrostatic/seat test) referencing the valve size.
What are typical minimum order quantities (MOQs)?
MOQs vary by supplier and customization level; standard stocked DN150 wafer/lug valves may be available in low quantities, while custom materials, coatings or special testing often have higher MOQs—confirm with each manufacturer.
Which certifications should I request for DN150 butterfly valves?
Request compliance documentation for the standards relevant to your project (e.g., EN 593, API 609, AWWA C504) and material certificates (EN 10204) for wetted parts when required.
What drives lead time for DN150 butterfly valves?
Lead time is driven by material availability (special alloys), seat/disc customization, required testing/certification, and current production queue—confirm estimated lead time when requesting a quote.
