VKF41.200C-MH Siemens Valve

Overview

The Siemens VKF41.200C-MH is a high-capacity, flanged butterfly valve designed for the proportional flow control of air and various gases in industrial combustion systems. This 8-inch (DN200) valve is engineered for durability and precision, featuring a metallic tight-closing design that ensures minimal leakage. The “-MH” designation indicates that this specific model includes a factory-installed manual handle kit, allowing for manual flow restriction and positioning when an actuator is not being used.

Features

• Robust gray cast iron housing with stainless steel disk and shaft for long-term reliability
• Integrated manual handle kit with a locking mechanism and position indicator
• Metallic tight-closing disk designed to provide less than 0.7 percent leakage
• Bi-directional flow capability for versatile installation options
• Maintenance-free design suitable for demanding industrial environments
• Wafer-type construction for easy mounting between ANSI or DIN pipe flanges
