LHS & LHH Hydraulic Actuator

Brand: Limitorque
Request Information
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.
Features
  • Efficient design based on computational modelling and extensive experimental validation provides high performance with reduced size, weight, and consumption.
  • Symmetrical and canted scotch yoke types perfectly fit individual valve torque requirements.
  • Quick stroking time: less than 0.5 seconds, subject to technical evaluation.
  • Rugged heavy-duty fabricated carbon steel build epoxy painted and Electroless Nickel Plated (ENP) cylinders provide maximum protection against corrosion.
  • Dust/water proofing to IP66/IP66M and IP67/IP67M according to EN 60529.
  • 25-year design life and maintenance intervals up to six years, (depending on service conditions, proper installation, operation and maintenance) exceed industry expectations.
  • Modular construction allows easy on-site maintenance without special tools and without removal from the valve.
