VKF41.150C Siemens Valve

Overview

The Siemens VKF41.150C is a 6-inch (DN150) flanged butterfly valve specifically designed for controlling the flow of air and various types of clean gases, such as natural gas and propane. This wafer-type valve is engineered for integration into gas trains and industrial combustion plants, offering a metallically tight shutoff. It features a robust design that allows for mounting between common pipe flanges (PN6, PN10, or PN16) and can be operated manually with an optional handle or automated using Siemens SQM or SAL series actuators.

Features

• Metallically tight-closing disk ensures high sealing performance with minimal leakage
• Designed for wafer-style mounting between ANSI or DIN counter-flanges
• Bi-directional flow capability allows for flexible installation in various piping configurations
• Maintenance-free design with stainless steel disk and spindle for enhanced durability
• Compatible with a wide range of actuators including SQM33, SQM40, SQM45, and SQM50 series
• Integrated beveled disc design providing an 85-degree angle of rotation for precise throttling
