VKF41.100H-MH Siemens Valve

Overview

The Siemens VKF41.100H-MH is a high-temperature butterfly valve designed for the precise modulating control of gas and air flows in industrial combustion systems. This 4-inch (DN100) valve is specifically engineered to handle high-temperature media, such as flue gas recirculation (FGR) or hot air, and comes equipped with a manual handle for local control and adjustment. Its robust construction ensures reliable performance in demanding environments where precise flow regulation is required without the immediate need for an automated actuator.

Features

• Designed for high-temperature applications with specialized seals and materials
• Integrated manual handle kit (MH) for easy local flow adjustment and locking
• Swing-through disk design for minimal pressure loss and consistent modulation
• Metallic tight-closing mechanism to ensure effective flow shut-off
• Visual position indicator for at-a-glance monitoring of valve status
• Durable cast iron body with stainless steel internal components for long service life
• Maintenance-free internal mechanics designed for continuous industrial use
