Injection Valves Specification Example for Long-Haul Trucks: Load Rated Version

This is a worked specification for injection valves in a load rated version 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 load rated version version exists because the duty cycle on long-haul trucks is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — ABS Plastic, 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

  • injection moulding
  • laser cutting
  • heat treatment
  • cold forging
  • CNC machining
  • electroplating

Where this example applies

Programmes that run load rated version most often specify this build for long-haul trucks. Related applications include aftermarket retail, fleet maintenance, three-wheelers, export programmes, light trucks.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 1.5 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 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

Can you match an existing sample?

Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.

Can the specification be held on file?

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

What testing is included?

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

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