Siemens 276-06040 2.5 Inch Normally Open Stainless Steel Spring Return Valve Actuator 24V

The Siemens Building Technology 276-06040 is a 2.5-inch normally open valve actuator designed for commercial HVAC and building automation applications. This robust actuator features stainless steel construction for durability and corrosion resistance in demanding environments.

Key Features:

• 2.5-inch valve size compatibility for medium-flow applications
• Normally open (NO) configuration - valve opens on power failure for safety
• Spring return mechanism provides fail-safe operation
• 24V AC/DC power supply for flexible installation
• Stainless steel construction resists corrosion and withstands harsh conditions
• 125 PSI pressure rating for reliable performance
• Variable return (VR) spring design ensures consistent actuation force

This actuator is ideal for controlling chilled water, hot water, and steam applications in commercial buildings. The spring return feature ensures the valve returns to its normally open position during power outages, providing fail-safe operation for critical HVAC systems.
