VKF41.50H-MH Siemens Valve

Overview

The Siemens VKF41.50H-MH is a high-temperature, flanged butterfly valve specifically designed for the precise modulation and control of hot air and flue gas recirculation (FGR). This 2-inch industrial valve is part of the VKF41 series and comes equipped with a manual handle assembly, allowing for local flow restriction and manual control. Its robust construction features a cast iron body and stainless steel internal components, making it a reliable solution for demanding combustion environments where temperatures can reach up to 550 degrees F.

Features

• High-temperature compatibility designed to withstand gas temperatures up to 550 degrees F
• Integrated manual handle kit including a position indicator and a handle with clamping pieces to lock the valve in any position
• Wafer-style design suitable for mounting between ANSI or DIN pipe flanges
• Bi-directional flow capability allows for flexible installation in various piping configurations
• Maintenance-free internal mechanics with self-lubricating PTFE-filled bearings
• Stainless steel disk and shaft for superior corrosion resistance and durability
