Product catalog summary
Technical Data and Features
The EB-SYS single-acting pneumatic actuators are designed for ¼ turn valves and are maintenance-free. They feature a blow-out proofed shaft, torques compliant with EN ISO 5211, and an optical position indicator with integrated operator for limit switches. All fasteners are made of stainless steel, and the actuators are SIL 2 certified, with SIL 3 available as a redundant system according to IEC 61508. They are available in 'spring opens' and 'spring closes' versions, providing high opening and closing torques through a scotch-yoke concept. The actuators ensure operational safety and long service life due to precise machining of parts and feature spring cartridges for easy maintenance without special tools. They are ATEX certified (EX II 2 GD c Tx).
Specifications
Torque ranges from 35 to 3590 Nm, with travel limits adjustable between -8°/+3°. Limit switches and solenoid valve mounting comply with VDI/VDE 3845. The supply pressure ranges from 2.5 to 8 bar, with a supply quality of filtered compressed air, either dry or lubricated. The temperature range is from -20°C to +80°C (standard), with options for low and high temperatures. The valve interface is EN ISO 5211, and the actuator cylinder is made of anodized aluminum, with other coatings available upon request.
Performance and Adjustments
The EBRO Speed Control block allows adjustment of closing/opening times up to 60 seconds, depending on actuator size. The closing time varies by model, with the EB 5.1 having a closing time of 0.15 seconds and the EB 26.1 up to 2.0 seconds. Air consumption is calculated as filling volume multiplied by control pressure.
Component Parts
The document lists component parts for models EB-SYS (4.1 - 12.1) and EB-SYS (14.1 - 26.1), including actuator cylinders, pistons, end covers, drive shafts, yokes, bearings, and various seals and fasteners. Materials used include EN AW 6063 - T6 for actuator cylinders, EN AC 46000 for pistons and end covers, and various polymers and metals for bearings and seals.
Dimensions and Weights
Dimensions and weights are provided for each model, with details on diameter, height, length, and weight. For example, the EB 5.1 model has a diameter of 77 mm and weighs 2.4 kg, while the EB 26.1 model has a diameter of 350 mm and weighs 228.6 kg.
Conclusion
The EB-SYS pneumatic actuators are robust, versatile, and designed for a wide range of applications, offering high performance and reliability with minimal maintenance requirements.
Overview: The document provides technical specifications for EB-SYS single-acting pneumatic actuators, which are available in 'spring opens' and 'spring closes' versions. These actuators are designed according to IEC 61508 standards, achieving SIL 2 (SIL 3 as a redundant system).
