Description
Siemens Building Technology 254-01102 Overview
The Siemens Building Technology 254-01102 is a complete 2-way, normally closed valve assembly engineered for precision flow control in commercial HVAC hydronic systems. Combining a forged brass valve body with brass trim and an integrated non-spring return floating actuator, this assembly delivers reliable, long-service-life performance in heating and cooling applications.
Key Features
- 2-way, normally closed (NC) configuration for fail-safe system design
- 1/2″ NPT end connections for straightforward pipe installation
- 24Vac control voltage — compatible with standard building automation and HVAC control systems
- 0.63 Cv flow coefficient for precise, low-flow hydronic circuit control
- Equal percentage flow characteristic for stable, proportional control across the full stroke range
- Forged brass body with brass trim for corrosion resistance and durability
- Non-spring return floating actuator — holds last position on power loss
- Compact valve-and-actuator assembly for simplified installation and reduced component count
Application
The 254-01102 is ideally suited for terminal unit control in fan coil units, unit ventilators, and small air handling units where accurate two-position or floating-point flow modulation is required. The normally closed design ensures the valve defaults to a closed position upon loss of power, protecting the system from unintended flow.
