Product Overview
The Siemens VKF42.50 is a precision-engineered butterfly valve designed for reliable shut-off and control of fluids in industrial process and pneumatic systems. As part of Siemens’ renowned VKF42 series, this valve features a robust wafer-style body with a concentric disc and elastomer liner, ensuring bubble-tight sealing and low torque operation. The VKF42.50 is actuated by a manual lever or can be equipped with pneumatic or electric actuators for automated control. Its compact design and lightweight construction make it ideal for space-constrained installations, while the corrosion-resistant materials ensure long service life in demanding environments. This valve is a direct-fit replacement for OEM systems and is compatible with standard ISO 5211 mounting interfaces for actuator retrofits.
