Industrial Valves

Writing a valve specification for a power plant project, whether for a private facility expansion or a government-funded infrastructure bid through PhilGEPS, involves satisfying two requirements that do not always reinforce each other naturally. The specification has to be technically sound enough that the valves actually procured perform reliably in demanding power generation service. It […]

A valve that worked reliably for two years suddenly starts leaking past the seat. Another seizes partway through a routine actuation cycle. A third develops visible pitting on a disassembly inspection that nobody expected to find this early in its service life. None of these failures are random, and in geothermal and other high-pressure, high-temperature

Geothermal power generation runs on a fluid that is unusually hard on the equipment carrying it. Geothermal brine arrives from deep underground at high temperature and high pressure, carrying dissolved minerals, chlorides, and often hydrogen sulfide and carbon dioxide that make it meaningfully more corrosive than the process fluids most industrial valves are designed around.
