valve trim
3 in-depth engineering guides on valve trim — specification, selection, testing and procurement.
Everything on valve trim
Vajra's engineering team has published 3 technical guides covering valve trim for industrial valve selection, specification, testing and procurement. Browse the full set below.
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.
Valve Hardfacing & Surface Coatings: Stellite, Tungsten Carbide & ENP
The valve body may be carbon steel, but the seats, gate, and stem live or die by their surface. Hardfacing and engineered coatings deliver wear, galling, and corrosion resistance where it matters. This guide compares the main options.
Valve Trim Selection: Soft Seat vs Metal Seat - A Technical Guide
Choosing between soft seat and metal seat trim is one of the most critical decisions in valve specification. Soft seats provide bubble-tight shut-off but are limited by temperature and abrasion; metal seats endure extreme temperatures and erosive service but require tighter machining tolerances. This guide breaks down the key differences.
