Everything on safety valves
Vajra's engineering team has published 3 technical guides covering safety valves for industrial valve selection, specification, testing and procurement. Browse the full set below.
HIPPS Valves: High Integrity Pressure Protection System Design and Selection
A High Integrity Pressure Protection System replaces or supplements relief valves by closing off the source of overpressure before a rupture can occur. This guide covers the final-element valve requirements that make a HIPPS certifiable.
API 526 Safety Relief Valve Sizing Guide - Orifice Letters, Set Pressures & Back Pressure
API 526 establishes the purchasing standard for flanged spring-loaded safety relief valves used in refinery and chemical plant service - defining orifice letter designations, face-to-face dimensions, flange ratings, and inspection requirements. This guide explains the full API 526 framework alongside API 520 sizing principles for engineers specifying pressure relief devices.
Pressure Relief Valve Sizing and Selection: API 520 & API 521 Guide
Pressure relief valves (PRVs) are the last line of defence against vessel overpressure. Correct sizing per API 520 Part I and API 521 is critical for plant safety, regulatory compliance, and avoiding costly undersizing or oversizing errors.
