Description
The Siemens Building Technology 599-10322 is a high-performance two-way ball valve engineered for precise flow control in commercial HVAC and building automation hydronic systems. Designed with an equal percentage flow characteristic, this valve delivers consistent, proportional control across its full operating range — making it an ideal match for modulating actuators in variable-flow heating and cooling applications.
Construction & Materials
- Robust brass body for corrosion resistance and long service life
- Chrome-plated brass ball for smooth, reliable operation and reduced wear
- Brass stem for strength and compatibility with a wide range of system fluids
- 1-1/2″ NPT end connections for straightforward installation into standard piping systems
Flow & Performance
- Flow coefficient (Cv): 25 — supports high-flow commercial applications
- Two-way valve configuration for on/off or modulating flow control
- Equal percentage flow characteristic for precise, linear control response
Application
- Hydronic heating and cooling systems
- Building automation and HVAC control systems
- Compatible with Siemens valve actuators for fully integrated control
- Suitable for chilled water, hot water, and glycol system applications
