Technical Guides
What ASTM A262 and G48 actually measure for valve materials, when buyers should require them, and how to read the acceptance criteria sensibly instead of treating every certificate as a guarantee for the real service.
Technical Guides
A practical look at where valve operating torque comes from, how it is measured at the works, what changes it in service, and how to write torque acceptance into a purchase order without creating fiction.
Technical Guides
Chloride in hydrostatic test water has destroyed more stainless valves than many realize. This article explains the limits, the standards, and the drainage and drying practices that make a test safe from start to finish.
