Fire-tested valves are designed to limit external and through-seat leakage to the levels permitted by the applicable standard during and after a specified fire-test sequence. Widely used fire-test standards include API 607 for quarter-turn valves and valves equipped with nonmetallic seats, API 6FA for applicable API 6A and API 6D valves, and API 6FD for […]

Valve sizing comes down to one number: Cv. Or Kv if you are working in metric. Selecting an appropriate Cv or Kv helps achieve the required capacity, but control performance across the operating range also depends on valve characteristics, rangeability, actuator and positioner performance, and the installed system. Get it wrong, and you end up […]

Industrial valve standards establish the design, material, dimensional, testing, and pressure-temperature requirements that manufacturers and buyers use to specify, procure, and install valves safely across oil and gas, chemical, power, and water treatment industries. One of the most widely referenced design standards is ASME B16.34, covering flanged, threaded, and welding-end valves across all pressure classes. […]
