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. […]
