Siemens Building Technology 279-06041 Pneumatic Valve Actuator Assembly 3 Inch 125# Stainless Steel

The Siemens Building Technology 279-06041 is a Flowrite 599 Series pneumatic valve actuator assembly designed for HVAC and industrial building automation systems. This 2-way normally open globe valve assembly features a 3-inch flanged connection with ANSI Class 125 body rating and high-temperature stainless steel trim for durability in demanding applications.

Key Features:

• 2-way normally open configuration with 100 Cv flow coefficient
• 3-inch flanged end connections with ANSI Class 125 rating
• Stainless steel trim with high-temperature packing rated to 250°F
• Pneumatic spring-return actuator with 3-8 psi control signal
• Linear flow characteristic for precise modulating control
• 12-inch actuator stroke with fail-safe normally open operation
• 63 psi maximum close-off pressure rating

This valve assembly combines the 599-06041 valve body with the 599-01010 pneumatic actuator to provide reliable, modulating control of water and other compatible fluids in commercial building HVAC systems. The normally open fail-safe position ensures flow continues in the event of air pressure loss, making it ideal for heating and critical process applications.
