The versatile pneumatic actuator for automation of valves

Product catalog summary
Overview: The document provides detailed information about the versatile pneumatic actuator designed for the automation of valves. It highlights the technology, variants, certifications, and key features of the actuator, emphasizing its adaptability and robust construction.
Specifications: The actuator supports swivel angles of 90°, 120°, 135°, and 180°, with extended angle adjustment in end positions. It operates in temperatures ranging from -40°C to +160°C and is SIL 3/PL capable. The casing is made of hard-coated aluminum alloy, with corrosion-protected steel shafts and stainless steel screws.
Certifications: The actuator is SIL 3 certified by TÜV Rheinland, compliant with IEC 61508 standards, and holds EAC-Certification for various automated valve types. It also meets VDI/VDE 3845 (NAMUR) and EN ISO 5211 standards for interface compatibility.
Design and Construction: The actuator features a robust design with a high-quality powder coating for use in aggressive environments. It includes a standardized interface for signal and control devices, a position indicator, and configurable end positions. The octagonal pinion connection allows for space-saving construction.
Functionality: The actuator is suitable for a wide range of applications, offering 18 different sizes and torques from 2 to 13,040 Nm. It supports flexible automation with two ISO flange patterns per actuator size and features a simple assembly and disassembly process for safety springs.
Applications: The actuator is used in the automation of ball and butterfly valves in process-oriented industries, including chemical applications and metal part treatments. It is compatible with various valve types, including stainless steel and brass automatic valves.
Additional Information: The document notes that the actuator's distinctive shape is patent protected, and it emphasizes the importance of the SIL 3 certification for increased failure safety. The company reserves the right to make technical changes without prior notice.
