Vajra's engineering team has published 4 technical guides covering API 602 for industrial valve selection, specification, testing and procurement. Browse the full set below.
Cast vs Forged Valve Bodies - Engineering Comparison, Applications and When to Specify Each
The choice between a cast valve body (shaped by pouring molten metal into a mould) and a forged valve body (shaped by pressing or hammering heated metal billet under high pressure) affects mechanical strength, size range, lead time, cost, and the applicable design standard.
API 6D vs API 600 vs API 602 Gate Valve - Key Differences Explained
API 6D, API 600, and API 602 all cover steel gate valves but for very different applications - pipeline, process plant, and compact forged respectively. This guide explains which to specify.
Gate Valve Types: Wedge, Slab, Knife Gate, OS&Y and More
Gate valves come in dozens of configurations - solid wedge, flexible wedge, slab gate, through-conduit, knife gate, rising stem, non-rising stem. Choosing the wrong type for your service leads to premature wear, seat leakage, or operational problems. This guide covers every gate valve type with applications and selection criteria.
Forged vs Cast Valve Body: Which Should You Specify?
Forged and cast valve bodies have different mechanical properties, pressure ratings, and cost structures. Understanding when to specify each - and what the relevant standards require - is fundamental to good valve specification.
