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
