Valve Selection
Valve Selection
Valve selection is about matching valve type, body material, trim, and actuator to the service conditions, so the valve performs reliably for its full design life. This tag collects decision-oriented articles on choosing the right valve for steam, water, gas, corrosive, and slurry services, plus comparison guides that weigh ball, gate, globe, butterfly, and check valves against specific requirements. Content emphasizes pressure and temperature limits, flow characteristics, maintenance expectations, and cost considerations, with selection tables and checklists. Written for engineers who need clear criteria rather than marketing claims.
