Description
The Siemens Building Technology 599-03168 is a 2-way, normally open globe valve engineered for precise flow control in commercial HVAC hydronic systems. Featuring an equal percentage flow characteristic, this valve delivers accurate, proportional modulation of heating or cooling media — making it an ideal choice for variable flow applications in air handling units, fan coil units, and heat exchangers.
Constructed with a durable bronze body and brass trim, the 599-03168 is built to withstand the demands of continuous commercial service while resisting corrosion in water-based hydronic systems. The 1-1/4″ NPT end connections allow for straightforward installation into standard piping configurations, and the 16 Cv flow coefficient ensures adequate flow capacity for medium-sized terminal equipment.
Key Features
- 2-way, normally open (NO) configuration — valve opens on loss of actuator signal for fail-safe operation
- Equal percentage flow characteristic for precise, stable modulation across the full control range
- 1-1/4″ NPT threaded end connections for easy installation
- 16 Cv flow coefficient — suited for medium-capacity hydronic terminal applications
- Bronze body construction for corrosion resistance and long service life
- Brass trim for reliable sealing and durability
- Designed for use with compatible Siemens valve actuators
Typical Applications
- Commercial HVAC hydronic heating and cooling systems
- Fan coil units and air handling units
- Heat exchangers and terminal units
- Building automation and direct digital control (DDC) systems
