Ball valves provide on/off isolation with a quarter-turn motion and very low pressure drop in the open position. Selection centers on bore (full vs. reduced), seat type (soft vs. metal), fire-safe/anti-static provisions for flammable service, and the end-connection standard. Confirm the pressure-temperature envelope and body/trim material against the process media before specifying.
Q: What is a ball valve used for?
A: Ball valves are primarily used for on/off isolation of liquids and gases where a tight shutoff and low flow resistance are required. They are common in pipeline, process, and utility services.
Q: Which standards govern ball valves?
A: Commonly referenced standards include API 608 (steel ball valves), API 6D (pipeline valves), ISO 17292, and BS 5351. The applicable standard depends on service and project specification.
Guidance reflects general engineering practice for ball valves; confirm against the project specification and applicable standards before procurement.
