Product Overview
The Siemens VKF42.350 is a high-performance butterfly valve engineered for precise flow regulation and shut-off control in industrial process and pneumatic systems. Manufactured by Siemens, a global leader in automation and control technology, this valve features a robust wafer-style body design that ensures a compact installation footprint while maintaining excellent sealing integrity. The VKF42.350 operates on a quarter-turn rotational mechanism, utilizing a precision-machined disc to modulate fluid or gas flow with minimal pressure loss. Its design is optimized for integration into building automation, HVAC, and general industrial process loops, providing reliable performance in both modulating and two-position control applications. The valve is compatible with a range of Siemens actuators, enabling seamless electrical or pneumatic actuation for automated system control.
