Overview

Pumps and valves combine castings and forgings with precisely machined sealing surfaces, shafts and trims. Parts must be leak-tight, pressure-rated and made from materials that suit the media — from water to hydrocarbons and chemicals.

Türkiye has a large pump and valve industry and a strong base of foundries, forging shops and machining suppliers, exporting to Europe and the Middle East.

On Metraxio you describe the part, attach drawings and state material, pressure class and quantity. The platform structures the requirement and shows which facilities are a technical fit.

Pump and valve parts are defined by pressure, media and material. Castings and forgings must be machined to tight sealing surfaces, and pressure testing is usually required. Stating the pressure class, media, material grade and test requirements helps identify facilities with the right casting and machining capability.

Typical parts & components

  • Pump casings and impellers
  • Valve bodies, bonnets and discs
  • Balls, stems and trims
  • Shafts, sleeves and bushings
  • Flanges and fittings
  • Actuator housings and brackets
  • Seals, seats and wear rings

The processes, materials and requirements below are an editorial reference of what is typical for pumps, valves & flow control programs — not a statement about facilities in the Metraxio network.

Typical materials & grades

Certifications & compliance

What buyers in this industry commonly ask suppliers for. Exact requirements depend on the program, customer and part.

Supplier certifications

  • ISO 9001 Typically required

    Baseline quality system.

  • API Spec Q1 Sometimes requested

    For oil and gas valve programs.

  • ISO 14001 Sometimes requested

    Requested by some OEMs.

Standards & regulations

  • Pressure Equipment Directive (PED) Common

    EU Pressure Equipment Directive.

  • EN 10204 Type 3.1 Typically required

    Material certificate for metallic raw material.

  • NACE MR0175 / ISO 15156 Sometimes requested

    Materials for sour service.

Quality & documentation

  • Hydrostatic shell and seat testing.
  • Material certificates to EN 10204 3.1.
  • NDT of castings where specified.
  • PED compliance for valves above the thresholds.
  • Sour-service compliance to NACE MR0175 where required.

Typical tolerances & surfaces

  • Sealing surfaces: fine finishes, often Ra 0.4–0.8 µm.
  • Shafts and sleeves: typically ±0.01–0.02 mm.
  • Flanges: dimensions per EN 1092-1 or ASME B16.5.
  • Impellers: dimensional and balance tolerances per drawing.

Sourcing from Türkiye

Türkiye combines a deep contract-manufacturing base with short routes into Europe. Industrial goods move between Türkiye and the EU under the customs union, so buyers typically avoid EU import duties on qualifying parts.

  • Many European destinations can be reached by road within several days; actual transit depends on origin, destination, customs handling and cargo.
  • Common delivery terms are EXW, FCA and DAP; Metraxio keeps the agreed Incoterm attached to the quotation and order.
  • Castings need pattern or tooling lead time; plan it into the first delivery date.

How Metraxio qualifies suppliers

Every request is checked against each facility's structured profile before any supplier is invited.

  • Hard criteria: the required process (e.g. casting, forging or CNC machining), the specified material and grade, and requirements such as PED or API Q1.
  • Missing data is not a rejection. If a facility profile does not yet state something, the result is "Needs More Information" rather than "Not Qualified".
  • No match yet? You can continue with Managed Sourcing and the Metraxio team runs supplier discovery for you.
  • Facility identities stay anonymous during the technical assessment.

Example project

How a typical request moves through Metraxio

400 stainless ball-valve bodies — 316 — PED — delivered DAP.

  • The buyer uploads drawings for investment-cast and machined valve bodies.
  • Metraxio structures the requirement: casting, CNC machining, stainless steel 316, pressure testing, PED and DAP delivery.
  • The fit assessment shows which facilities are qualified, which need more information and which do not match.
  • The buyer invites qualified facilities to a Supplier RFQ, or hands the job to Managed Sourcing.

Frequently asked questions

Can suppliers pressure-test valves?

Many valve-part suppliers test shells and seats in-house; list testing in your requirement.

Which casting methods are common?

Sand casting for large bodies and investment casting for smaller stainless parts.

Are sour-service parts possible?

Yes, where material and hardness meet NACE MR0175 limits. State it in your requirement.

Which materials are typical?

Ductile iron, carbon steel, stainless 316, duplex, bronze and brass depending on the media.

Are supplier names visible during the assessment?

No. Facilities are shown anonymously during the technical assessment. Identities are shared as the engagement progresses.
