VKF41.100C-MH Siemens Valve

Overview

The Siemens VKF41.100C-MH is a 4-inch (DN100) flanged butterfly valve specifically designed for the proportional control of gas and air flow in combustion plants. This wafer-type valve is engineered to be mounted between standard pipe flanges and comes equipped with an integrated manual handle kit, allowing for precise local flow restriction and manual control. Its robust construction ensures reliable performance in demanding industrial environments, providing a metallic tight shutoff to minimize leakage.

Features

• Manual handle kit included for local adjustment and locking in any position
• Integrated visual position indicator for easy monitoring of valve status
• Metallic tight-closing design with less than 0.7 percent leakage at shutoff
• Constructed with a durable grey cast iron housing and stainless steel disk and shaft
• Maintenance-free internal mechanics designed for long-term industrial use
• Versatile mounting compatibility between PN6, PN10, and PN16 flanges
