  • Motor Actuated Valve Application Guide Ball Valves
    , globe or butterfly valves can be used for this application. The pressure drop across the valve should be low (usually less than 2 PSI) in. its open position. Valves for this purpose are typically selected at line size to minimize installation. cost and pressure drop. In some applications, ball
