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
- 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
