Everything on procurement
Vajra's engineering team has published 3 technical guides covering procurement for industrial valve selection, specification, testing and procurement. Browse the full set below.
Valve Selection Checklist: 10 Parameters Procurement Engineers Must Specify
Incomplete valve specifications are the single biggest cause of delivery delays and wrong-material supplies. This checklist covers 10 parameters every valve RFQ must define - from line class to fire-test certification.
How to Read a Valve Datasheet - Complete Field-by-Field Guide
A valve datasheet is the single document that defines every aspect of a valve - from its physical size and material to its operating limits and test requirements. Knowing how to read and verify each field is essential for engineers raising purchase specifications and for procurement teams reviewing supplier submittals.
Valve Piping Classes and Specification Sheets: A Complete Engineering Guide
Piping classes (pipe specs) are the backbone of process plant valve procurement - they define which valve types, materials, end connections, pressure classes, and inspection requirements apply to every pipe in the plant based on fluid service and operating conditions. This guide explains how piping classes are structured and how to translate them into accurate valve orders.
