VALBIA SR100S.05 82SR0018 Pneumatic ActuatorThe high-quality aluminum alloy cylinder body is extruded, with precision-machined internal holes and external surfaces treated with hard anodizing (in special cases, anodizing + Teflon coating), resulting in a longer service life and low friction coefficient. The integrated design ensures that all double-acting and single-acting actuator models share the same cylinder body and end covers, making it convenient to change the action mode by adding or removing springs. The modular pre-loaded safety spring set allows for easy and safe installation or adjustment of the number of springs, both during assembly and on-site. Two separate adjustment screws on the external side provide precise and convenient adjustment of the valve open and closed positions for actuators already installed on valves. For full-stroke adjustment, longer adjustment screws are additionally configured on both end covers. The multi-functional position indicator offers on-site visual indication, complies with VDI/VDE3845 and NAMUR standard slots, and can accommodate and output all accessories, such as limit switch boxes, electrical positioners, and position sensors (Pepperl+Fuchs, Turck). The air source interface complies with NAMUR standards, allowing direct installation of NAMUR standard solenoid valves. Composite material bushings on the back of the rack, piston guide rings, and output shaft bearings prevent metal-to-metal friction and enhance lubrication, ensuring low friction and long life. All fasteners are made of stainless steel for long-term corrosion resistance. The connection parts comply with the new international standard specifications ISO5211 and DIN3337 (F03-F25), ensuring interchangeability and universality in product installation.
