Description
Siemens Building Technology 254-01119 Valve Assembly Overview
The Siemens Building Technology 254-01119 is a complete 2-way normally open valve assembly engineered for precise hydronic and HVAC control applications. Combining a forged brass body with brass trim and a non-spring return floating actuator, this assembly delivers reliable, long-lasting performance in commercial and light industrial building automation systems.
Key Features
- 2-way, normally open (N/O) valve configuration for fail-safe flow control
- 1/2″ NPT end connections for straightforward installation into standard piping systems
- 24 Vac actuator power supply — compatible with standard BAS and DDC control systems
- 1.0 Cv flow coefficient for accurate, low-flow hydronic applications
- Equal percentage flow characteristic for stable, linear control response across the operating range
- Forged brass valve body with brass trim for corrosion resistance and durability
- Non-spring return floating actuator — maintains last position on power loss
- Factory-assembled valve and actuator combination for simplified installation and commissioning
Application
Ideal for use in fan coil units, air handling units, heat exchangers, and other hydronic terminal equipment where precise two-position or floating point flow modulation is required. The equal percentage flow characteristic ensures consistent control authority across a wide range of system conditions, making it well-suited for variable-flow building automation systems.
