Siemens Building Technology 277-06040 2.5" Flanged Normally Open Butterfly Valve with 8" Actuator

The Siemens Building Technology 277-06040 is a 2.5-inch flanged butterfly valve designed for HVAC and building automation applications. This normally open (N/O) valve features 125-pound ANSI flange connections and stainless steel construction for durability and corrosion resistance in commercial and industrial environments.

Key Features:

• 2.5-inch valve size with 125# ANSI flange connections for secure piping integration
• Normally open configuration - valve closes when actuator is energized
• Stainless steel construction provides excellent corrosion resistance
• 8-inch stroke actuator provides reliable modulating or two-position control
• Designed for chilled water, hot water, and glycol solution applications
• Suitable for building automation and HVAC control systems

This valve assembly is ideal for flow control in heating, cooling, and process water systems where reliable shutoff and modulating control are required. The flanged connection design allows for easy installation and maintenance in commercial building mechanical systems.
