LimitorqueTM LPSLimitorque Pneumatic Scotch Yoke Heavy-Duty Actuator
Quality, Dependability and ProductivityFlowserve Limitorque makes valve control easierin ways as diverse as the applications in which itsproducts are used. LPS pneumatic actuators deliverup to 250 kNm* (184 000 ft-lb) of precisely controlledtorque — safely automating valves for all types ofapplications, including HIPPS (High-Integrity PressureProtection Systems).Available in a wide range of materials suitable for usein the most demanding conditions, LPS actuators arecomplemented by a comprehensive range of control systems,including ESD, PST, Line-Break and Quick-Closing options.A suite of standard controls systems is available for shortdelivery, but the Limitorque engineering team can designcustom solutions for the largest and most complex customerrequirements.Today’s industry requirements are more rigorous than everbefore. Nowhere is this more evident than in the Oil andGas industry where new requirements are incorporatedinto project specifications almost every day. Limitorque hasaddressed these demanding requirements in the design oftheir latest product, the LPS actuator. This makes the LPSthe most technically advanced and market-compliant actuatoravailable anywhere in the world.* For higher torque ranges, consult factory.2The LPS actuator features a 25-year design life dependingon service conditions, proper installation, operation andmaintenance. In order to achieve this industry-leading designlife, in-field maintenance is prescribed to be performed everysix years of operation. For high-cycle applications, such ascontrol valve operation, more frequent maintenance of thereplaceable wear surfaces, as outlined in EN 15714, may berequired.To complete the automation package, LPS actuators areavailable with accessories such as lockout modules and gearoverrides. Limitorque provides engineering design services formounting hardware, ensuring that your actuation solution isready to handle the toughest challenges.
