About this product

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.

Features and Benefits

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 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
