Description
Siemens 254-01106 Two-Way Normally Closed Valve Assembly
The Siemens 254-01106 is a precision-engineered two-way, normally closed valve assembly designed for reliable flow control in commercial HVAC hydronic systems. Featuring a forged brass body with brass trim, this valve delivers long-lasting durability and corrosion resistance in demanding building automation applications. The integrated non-spring return floating actuator operates on 24Vac, making it compatible with a wide range of building automation and control systems.
Key Features
- Two-way, normally closed (NC) valve configuration for fail-safe operation
- 1/2″ NPT connection for straightforward installation into standard piping systems
- 24Vac actuator voltage — compatible with most commercial BAS and HVAC control panels
- 1.6 Cv flow coefficient for precise, low-flow hydronic applications
- Equal percentage flow characteristic for accurate and stable modulating control
- Forged brass body construction for superior strength and corrosion resistance
- Brass trim for added durability and compatibility with hydronic media
- Non-spring return floating actuator — maintains last position on power loss
- Designed for integration with Siemens Building Technology control systems
