The pneumatic P5 and the electro pneumatic EP5 are fast and accurate general purpose positioners available in pneumatic (P5) or electropneumatic (EP5) configurations.Choose from explosion-proof (EP5-EX), fail freeze (EP5-FS) and intrinsically safe (EP5-IS) options.
The Flowserve Logix 2000 is a digital positioner with on-board PID control. Communications are either 4-20 mA or Modbus. A PID controller mounted on the valve updates the valve stem position 16 times per second thus reducing control system lag. The Logix 2000 has error reporting capabilities and extensive valve diagnostics. The unit is completely configurable through the user interface screen, no external configuration device needed.
The Flowserve Logix® 3400MD Digital FOUNDATION® Fieldbus positioner utilizes state-of-the-art piezo technology to provide superior performance and reliability. The Logix® 3400MD can be easily configured using the local buttons or the ValveSight DTM. Logix® 3400MD has a complete diagnostics package that can alert the user to developing conditions that may cause unnecessary upset conditions in the plant.
The Flowserve Logix 420 Series of Digital HART® positioners utilize state-of-the-art piezo technology to provide superior performance and reliability. The Logix 420 series can be easily configured using the optional LCD and local buttons, HART handheld, and ValveSight DTM software.
The Limitorque Direct Gas powered scotch yoke actuator series LDG is specifically designed to be operated by high pressure natural gas, or any other high pressure pneumatic fluid up to a maximum of 105 barg (1500 psig). LDG actuators are ideal for pipeline applications where no external sources of motive power are present and provide a robust heavy duty design and long service life with industry leading maintenace intervals. This makes them the actuator of choice for installation in remote or unmanned facilities.
The Flowserve Limitorque WG series of worm gearboxes is designed for quarter-turn butterfly, ball, and plug valve applications as well as quarter-turn and multi-turn dampers and offers unsurpassed quality and longevity in a wide variety of weatherproof, submersible and buried-service applications.
The Limitorque Hydraulic Scotch Yoke actuator series LHS and LHH are designed to meet or exceed the most current and stringent safety and reliability standards for application in the oil and gas industry. LHS and LHH are ideal where hydraulic motive power is preferred for the operation of quarter-turn valves and for applications requiring a robust heavy duty design, long service life, high-torque and high-speed operation.
DeviceNet™ uses CAN (Controller Area Network) for its data link layer and CIP™ (Common Industrial Protocol) for the upperlayers of the network. DeviceNet supports multiple communication hierarchies and message prioritization, and can be configured to operate in a master-slave or a distributed control architecture using peer-to-peer communication to perform actuator process control and feedback data retrieval.
Limitorque actuators with Foundation Fieldbus can act as a link active scheduler and time master for regulating communication on a fieldbus segment. The Fieldbus Foundation has tested and registered the Limitorque Device Description (DD) files to ensure interoperability with registered devices from multiple vendors. In addition, The FDT Group has certified the DTM (Device Type Manager) for use with both standalone and non-standalone frames.
