Another Limitorque LPS-20 is ready for dispatch. This unit was built by Acrodyne Pty Ltd under the modular program to suit the exact requirements of the customer.
The scope included the mounting of the valve, fitting, piping, and calibrating a Siemens positioner, and installation of an AcroMatic volume booster.
This configuration provided a 4-second open and 8-second close time.
Limitorque’s LPS heavy-duty pneumatic scotch yoke actuator is the innovative, reliable choice for on/off, inching, and modulating automation applications on quarter-turn medium-to-large sized valves in general and protective services for the oil & gas market.
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.
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 of 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.
