  • How to Choose a Control Valve
    , valve sizing is not an exact science, but is the result of making the best selection from available options. Characterized "V" Ball valves provide the high precision throttling and rangeability needed for liquid and gas control ap-. plications, where a streamlined flow passage allows for high
  • Optimizing Gas Systems with Optimux Control Valves
    As more and more natural gas is produced and brought to market around the world, gas handling, processing, and distribution systems must respond by pushing the envelope to ensure maximum capacity where and when it is needed. It follows that the requirements for control valve applications
  • Spraywater Control Valves
    better control and a more efficient operation. 2. Because of the wide range of flows, ensure that the valve is capable of properly. throttling across the entire range. Torque seated valves have problems throttling. at both the low and high end of their operating range. Care must also be taken
  • Energy Saving Control Valves
    control valve actuation. This discussion will show comparisons between two methodologies, and will assist the reader in making better-informed decisions about control valve actuation.
  • Pressure Independent Control Valves
    In HVAC plants, water distribution can be accomplished at constant. or variable fl ow. Each type of distribution system has advantages and. disadvantages. Today variable fl ow systems using electronic 2-way. control valves became generally accepted as the industry standard due. to their benefi ts
  • The basics of pneumatic control valves
    of classifying directional-control valves is by the flow paths under various operating conditions. Important factors are the number of possible valve positions and the number of ports and flow paths. Here are some basic configurations. consist of two ports connected with a passage that can be opened
  • Selection Considerations for Control Valves Versus Regulators
    In any control system, the option potentially exists to select either a control valve or a regulator and it is useful to compare the respective performance and economics of these approaches to arrive at some general selection guidelines. Unlike regulators, control valves are not standalone products
