    Compact HART Digital
  • The Flowserve Logix 520MD+ Digital HART Positioner utilizes state-of-the-art piezo technology to provide superior performance and reliability. The Logix 520MD+ Positioner is designed to withstand severe environments; it is equipped with over 130 helpful warning alarms that can warn against potential failure of the valve, actuator, and positioner. When utilized with the ValveSight DTM Software many diagnostic tools are available to quickly diagnose problems and potential issues.
    3rd Generation HART Digital
  • The Logix 520MD Series digital positioner combines superior positioning and tuning functions with convenient setup and powerful diagnostic tools. The Logix 520MD positioner uses a multi-variable gain tuning algorithm which allows the positioner to make large step changes with minimal overshoot while achieving the resolution to respond to very small step changes. The Auto-tune procedure cycles the actuator to produce a measured response and selects gain values that provide appropriate actuator performance. The Auto-tune function includes a gain modifier selector that can be used to increase or decrease the calculated gain in order to achieve optimal performance. Easy DIP switch configuration for tuning mode and other common settings. For custom settings, tuning sets can be modified with a handheld or with ValveSight software, to accommodate a wide range of actuator sizes and types.
    2nd Generation HART Digital
  • The Valtek XL Series (XL and XL90), two-stage positioners offer fast and sensitive dynamic response characteristics to meet extremely demanding control objectives. The positioners are available with either an electro-pneumatic (I/P) transducer module for milliamp current control signals or a pneumatic module for aircontrol signals. Designed for high performance, these positioners are field reversible and ruggedly built for reliability in severe industrial environments.
    Analog Electro-Pneumatic
  • The Beta positioner is a single or double-acting, force balanced instrument that provides fast, sensitive and accurate positioning of diaphragm or cylinder actuators. It is available with either a pneumatic module for air control signals or an electro-pneumatic (I/P) module for milliamp current control signals. Designed for high performance, this positioner is compact, field reversible and ruggedly built for reliability in severe industrial environments.
