C-MAX C-250DA 120PSI Double-Acting Pneumatic Actuator

The C-MAX C-250DA 120PSI double-acting pneumatic actuator is powered by compressed air. It drives the gear transmission of the output shaft through the linear motion of the piston rack, providing angular stroke output. Available in both double-acting and single-acting types, it is widely used for the switching and regulation of angular stroke valves such as ball valves, butterfly valves, and plug valves. It is also suitable for other rotary applications and is an ideal device for achieving automated control in industrial pipelines.

The C-MAX C-250DA 120PSI double-acting pneumatic actuator is a pneumatic actuator powered by compressed air, which drives the gear transmission of the output shaft through the linear motion of the piston rack, and outputs with angular stroke. It has double acting and single acting types and is widely used for opening and adjusting angular stroke valves such as ball valves, butterfly valves, and plug valves. It can also be used in other rotary situations and is an ideal device for achieving industrial pipeline automation control.

The C-MAX C-250DA 120PSI double-acting pneumatic actuator features a high-quality extruded aluminum alloy cylinder body. The precision-machined internal bore and external surface are hard anodized (with Teflon coating under special conditions), ensuring long service life and a low friction coefficient. Its integrated design allows all double-acting and single-acting actuator models to share the same cylinder body and end covers, making it easy to convert between action types 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 in the field. Two separate external adjustment screws provide exceptional convenience for actuators already installed on valves, enabling adjustment of the valve open and closed positions. For full stroke adjustment, longer screws are provided on both end covers. The multi-functional position indicator offers visual on-site indication and complies with VDI/VDE3845 and NAMUR standard slots, allowing installation and output of 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, enabling direct installation of NAMUR standard solenoid valves. Composite bushings on the back of the rack, piston guide rings, and output shaft bearings prevent metal-to-metal contact, enhance lubrication, and ensure low friction and long service life. All fasteners are made of stainless steel for long-term corrosion resistance. The connection parts comply with the latest international standards ISO5211 and DIN3337 (F03-F25), ensuring interchangeability and universality during installation.
