Define fluid, pressure, temperature, material, actuation and connection requirements for suitable valves.

Content reviewed on 26 August 2026

What is Valves and flow-control equipment used for?

Valves isolate, regulate or direct a fluid. Valve type, body, seals, pressure, temperature, actuation and connections must match the fluid and operating duty.

Typical applications

Water supply and treatment
HVAC installations
Industrial processes
Irrigation and fire networks

Technical comparison

Criteria that should appear in every quotation

Valves isolate, regulate or direct a fluid. Valve type, body, seals, pressure, temperature, actuation and connections must match the fluid and operating duty.

Describe your needs

Comparison criterion

Define valve type, fluid, nominal diameter, pressure, temperature and flow direction.
Compare body material, seats, seals, connections, operating torque and leakage class.
Verify standards, hydrostatic tests, material certificates and actuator compatibility when required.
Check marking, corrosion protection, spare parts and maintenance instructions.

Supplier file

Official datasheet showing the exact reference, dimensions, materials and declared performance.
Certificates and test reports applicable to the product and destination market.
Warranty terms, exclusions, duration, claim procedure and spare-parts availability.
Packing plan, labelling, quantity per package, dimensions and logistics weight.

Pre-shipment checks

Verify references, quantities and conformity with the approved sample.
Inspect appearance, dimensions, assembly, finish and markings against the specification.
Run functional tests or measurements on an agreed sample before release.
Check packing, accessories, documents and transport protection.

Prepare supplier outreach

The information needed to compare supplier offers properly.

A precise request reduces pricing gaps, technical misunderstandings and corrections after sampling.

Specifications

Dimensions, materials, performance, tolerances, finishes, standards and acceptance criteria should be written before manufacturers are contacted.

Supplier capability

MOQ, output, lead time, equipment, subcontracting, warranties, spare parts and references reveal whether the supplier can deliver.

Approval

Samples, tests, documents, labels, packaging and the inspection plan should be approved before production or shipment.

The TRASOU method

From requirements to controlled delivery

Define

Product, quantity, target quality, budget, country and schedule.

Compare

Suppliers, quotations, capacity, documents and terms.

Verify

Samples, compliance, production, packaging and risks.

Follow up

Decisions, documentation, shipment and expected delivery.

Frequently asked questions

Common questions about Valves and flow-control equipment

Can you work from an existing reference?

Yes. A photo, technical sheet, drawing, sample or supplier reference can be used as the starting point.

How is quality verified?

Acceptance criteria are defined before outreach and then applied to samples, documents and agreed inspections.

Is the minimum order quantity fixed?

No. MOQ depends on the manufacturer, product, customisation and packaging.
