Injection Valves Specification Example for Delivery Vans: Racing Spec

This is a worked specification for injection valves in a racing spec programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The racing spec version exists because the duty cycle on delivery vans is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Powder Coated Steel, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • anodising
  • ultrasonic cleaning
  • gravity casting
  • shot blasting
  • electroplating
  • robot welding

Where this example applies

Programmes that run racing spec most often specify this build for delivery vans. Related applications include fleet maintenance, long-haul trucks, agricultural trailers, passenger cars, camper conversions.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 4.0 sampling on the finished lot.
  • Finish inspection under agreed lighting.
  • Carton drop test on the first lot of a new packing specification.

Questions buyers ask

What is the minimum order quantity?

The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

What testing is included?

Standard lots ship with dimensional and hardness reports. IATF 16949 documentation is issued with the shipment when your market requires it.

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the IATF 16949-compliant build instead of a fresh interpretation.

How is packing specified?

Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
