What to specify in your RFQ

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

  • Nominal size and connection (DN and thread/ flange type)

    Specify DN 1½ and the exact connection standard (thread type or flange dimensions) so the manufacturer quotes the correct end fitting.

  • Pressure rating (PN)

    State PN16 explicitly and whether the valve must be rated across the full PN range (e.g., 0.8–16 bar) or for specific operating pressure.

  • Function (single-function / automatic air release)

    Confirm you need a simple/single-function automatic air release valve (small orifice only) versus combination or vacuum-capable models.

  • Materials and coatings

    List body, float and internal material preferences (cast iron, ductile iron, stainless steel, ABS, or specific coatings) for compatibility with potable, sea or wastewater.

  • Standards and inspection

    Specify required design/inspection standards (for example EN 1074, EN 12266 or any client-specific requirement) and test pressure acceptance criteria.

  • Operating media and temperature

    State the fluid type (potable water, raw water, sewage, sea water) and expected temperature range for material selection.

  • Quantity and delivery

    Provide the exact quantity, any batch/serial-numbering needs, target delivery date, and whether spares or maintenance kits are required.

Sourcing FAQ

How do I verify a supplier actually manufactures DN 1½ PN16 air release valves?
Ask for product datasheets, photographs of the valve with model numbers, an official catalogue or brochure (PDF) and confirmation that the product is made by the supplier (examples: company product pages or 'made in' statements). The provided search results include company product pages and brochures that serve as such evidence.
What is a typical minimum order quantity (MOQ) for simple air release valves?
MOQs vary by manufacturer and whether the valve is standard or customized; small standard valves are often available in single units, while custom-coated or bespoke configurations may have higher MOQs—confirm MOQ with each manufacturer.
Which certifications or standards should I request?
Request conformity to applicable design and inspection standards (for water-system valves commonly referenced: EN 1074, EN 12266) and any material/certificates required for potable water or marine environments; ask manufacturers for test certificates and material declarations.
What drives lead time for these valves?
Lead time is driven by whether the valve is standard off-the-shelf, material availability (stainless or special alloys), coatings/painting, customization, and current production backlog; request a lead-time estimate in the quote.
