This pneumatic actuator is designed for high performance and durability in industrial applications. It features a multi-functional position indicator with a NAMUR standard mounting groove, allowing easy integration of accessories like valve positioners and limit switches.
The output shaft is a high-precision one-piece gear made from nickel-plated alloy steel, compliant with ISO5211, DIN337, and NAMUR standards. It can be customized to meet specific size requirements, and stainless steel options are available for enhanced corrosion resistance.
The cylinder body is made from ASTM6005 extruded aluminum and undergoes hard oxidation treatment. Additional surface finishes such as epoxy coating, PTFE coating, or nickel plating are also available to suit different environmental conditions.
The end cap is a die-cast aluminum alloy component that comes in various colors with options for metal powder coating, PTFE coating, or nickel plating for added protection and aesthetics.
The pistons feature a double piston rack design, constructed from either cast aluminum with hard oxidation or cast steel with galvanization. This ensures symmetrical installation, fast response, long service life, and the ability to reverse the piston for directional control.
The stroke adjustment mechanism includes two independent external screws, allowing precise ±5° adjustment in both opening and closing directions for accurate positioning.
The actuator uses a high-performance combined preload spring made from premium materials with coating treatment and pre-press assembly. This ensures strong corrosion resistance, long service life, and safe disassembly for maintenance or spring replacement in single-acting models.
Low-friction, long-life composite materials are used for bearings and guides to prevent direct metal-to-metal contact, making maintenance and replacement easier.
Sealing is achieved using O-rings made from nitrile rubber at normal temperatures, while fluorine or silicone rubber is used for high or low temperature environments, ensuring reliable performance under varying conditions.
Whether you need a standard or custom solution, this actuator provides flexibility, reliability, and precision for a wide range of industrial applications.
