Italy VALBIA DA63+82DA0012 Pneumatic Actuator is a double-piston rack and pinion rotating structure pneumatic actuator. Yihong's pneumatic actuator is piston-type, with a long piston stroke, suitable for applications requiring high thrust. It can not only directly drive the valve stem but also be used in combination with worm gears and other mechanisms.

VALBIA DA63 Pneumatic Actuator, model 82DA0012, features a high-quality extruded aluminum alloy cylinder with precision-machined internal bore and external surface hard anodized (special cases include anodizing + Teflon coating), ensuring long service life and low friction coefficient. The integrated design allows all double-acting and single-acting actuator models to share the same cylinder and end caps, making it easy to change the acting mode by adding or removing springs. The modular pre-loaded safety spring set enables convenient 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 exceptional convenience for actuators already installed on valves, allowing adjustment of the valve open and closed positions. For full stroke adjustment, longer adjustment screws are provided on both end caps. The multi-functional position indicator offers on-site visual indication, compliant with VDI/VDE3845 and NAMUR standard slots, capable of mounting and outputting all accessories such as limit switch boxes, electro-pneumatic positioners, and position sensors (e.g., Pepperl+Fuchs, Turck). The air supply interface complies with NAMUR standards, allowing direct installation of NAMUR standard solenoid valves. Composite bushings on the rack back, piston guide rings, and output shaft bearings prevent metal-to-metal friction, enhance lubrication, and ensure low friction and long life. All fasteners are made of stainless steel for long-term corrosion resistance. The connection parts comply with the latest ISO5211 and DIN3337 (F03-F25) standards, ensuring interchangeability and universality in product installation.
