FAQs

Yes. KM/8025/MF/140 is ISO 6432 compliant, with a 25 mm bore and G1/8 port, and includes nose mounting nut and piston rod locknut as standard. This ensures straightforward, drop-in installation onto standardized mounting patterns, reducing retrofit time and risk during line upgrades.
The magnetic piston enables reliable, contact-free position sensing, enabling sensors to detect piston position without additional components. This reduces wiring complexity, improves control loop accuracy, and lowers installation and maintenance costs in automated lines.
Yes. The stainless steel barrel (1.4301) delivers high corrosion and acid resistance, making it well-suited for food processing and washdown environments. Its design supports hygienic standards, simplifying cleaning regimes and extending component life in sanitary applications.
KM/8025/MF/140 supports 1–10 bar (15–145 psi) and operates from -10 to 80 °C. This broad range allows reliable actuation across diverse facilities and conditions, provided the air supply is clean and dry and the piston cushioning is appropriately set for the cycle rate.
Leverage the built-in features: buffer cushioning to reduce wear, nose mounting with a locknut for quick, stable mounting, and the standard ISO 6432 footprint for easy replacements. Regular inspection of seals and bore surfaces, along with routine cleaning in washdown areas, helps sustain performance and lowers total cost of ownership.
