Valve Selection for Industrial Service

PRACTICAL GUIDE

Project context

Choosing valve type, materials and actuation for process duty. For projects in Afghanistan, early definition of operating conditions, site access, utilities, local skills and maintenance capability helps prevent avoidable procurement changes.

Planning and specification

Fluid, pressure, temperature, shutoff class, corrosion, solids content and operating frequency must be documented. Requirements should be recorded in a clear datasheet and linked to applicable standards, inspection stages, documentation, delivery conditions and acceptance criteria.

Typical equipment and supply scope

Gate, globe, ball, butterfly and check valves, actuators, positioners, gaskets and repair kits. The final package should also consider commissioning materials, recommended spares, special tools, training, warranty support and export packing suitable for the complete transport route.

Procurement approach

Comparable bids require one consistent technical scope. Supplier deviations should be listed separately, while drawings, certificates, test reports, country of origin, delivery schedule and after-sales support are evaluated before award.
