4 in-depth engineering guides on cavitation — specification, selection, testing and procurement.
Everything on cavitation
Vajra's engineering team has published 4 technical guides covering cavitation for industrial valve selection, specification, testing and procurement. Browse the full set below.
Restriction Orifice Plates: Sizing, Multi-Stage Design and Selection Guide
Restriction orifice plates limit flow or drop pressure with no moving parts. This guide covers single-stage and multi-stage sizing, cavitation and choked-flow limits, materials, and where they beat a control valve.
Control Valve Noise and Cavitation Control: Trim Selection and IEC 60534 Guide
High pressure drops make control valves cavitate and roar. This guide explains hydrodynamic vs aerodynamic noise, IEC 60534 prediction, and the source and path treatments - multi-stage trim, hardened materials, and downstream measures - that fix them.
Cavitation and Erosion in Valves: Damage Mechanisms and Prevention
Cavitation, flashing, and erosion are the leading causes of premature control-valve trim failure. Each has a distinct physical mechanism and a distinct set of remedies. This guide explains how these damage mechanisms work and the design and material strategies that prevent them.
Control Valve Selection Guide: Cv Calculation, Types & Actuators
Control valves are the workhorses of process automation - incorrect sizing or wrong valve type causes instability, cavitation, and premature wear. This guide covers Cv/Kv calculation methodology, IEC 60534 liquid and gas sizing, globe vs butterfly vs cage valve selection, trim characterisation, and positioner specification.
