VKF41.200H-MH Siemens Valve

Overview

The Siemens VKF41.200H-MH is an 8-inch high-temperature butterfly valve designed for demanding industrial combustion and HVAC applications. This specific model features a beveled disk with a metallic tight shut-off and is equipped with a manual handle (-MH) that includes a position indicator and a locking mechanism. Engineered for durability, it is primarily used to control the flow of hot gases, such as flue gas recirculation or hot air, in systems requiring precise regulation and reliable performance.

Features

• High-temperature construction optimized for flue gas recirculation and hot air systems
• Metallic tight-closing disk ensures minimal leakage through the fully closed valve
• Integrated manual handle (MH) with clamping pieces to lock the valve in any position
• Visual position indicator provides clear confirmation of the valve disc orientation
• Wafer-style body designed for easy installation between counter-flanges
• Robust stainless steel disk and spindle for enhanced corrosion resistance and longevity
