The Limitorque LDG Direct Gas powered scotch yoke actuator series 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 maintenance intervals. This makes them the actuator of choice for installation in remote or unmanned facilities.View Details Contact Us
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.View Details Contact Us
The Limitorque LHS and LHH Hydraulic Scotch Yoke actuator series 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.View Details Contact Us
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.View Details Contact Us
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.View Details Contact Us
HART® (Highway Addressable Remote Transducer) is a digital communication protocol that is based upon the Bell 202 telephone communication standard. By using FSK (frequency shift keying) to superimpose low level digital signals on top of an analog 4-20 mA signal, two simultaneous communications channels exist. The 4-20 mA signal communicates the primary measured value, and the digital signal communicates additional device information to the plant control system.View Details Contact Us
Limitorque actuators offer both variations of PROFIBUS in use today: PROFIBUS DP™ (Decentralized Peripherals) and PROFIBUS PA™ (Process Automation). PROFIBUS DP is used to operate sensors and actuators via a centralized controller in production (factory) automation applications.View Details Contact Us
Compatible with Limitorque non-intrusive MX multi-turn and QX quarter-turn actuators, the Profibus DP with Redcom network protocol complies with the Profibus specification 2.212_V and allows connection with a single or dual redundant channel networks (optional). The new and improved DTM (Device Type Manager) greatly reduces the time required for configuring and acquiring pertinent diagnostic information.View Details Contact Us
The Flowserve Limitorque QX, non-intrusive electric actuator is designed for a wide range of environmental applications in power, oil & gas, and water industries. The QX design builds on more than 20 years of proven MX technology to provide all the user-preferred features in a
quarter-turn smart actuator package.
