Description
The Siemens 599-10363 is a commercial-grade, three-way ball valve engineered for precise hydronic and HVAC system flow control. Featuring an equal percentage flow characteristic, this valve delivers consistent, proportional flow modulation across its full operating range — making it an ideal choice for heating and cooling coil applications where accurate temperature control is critical.
Key Features
- 1″ NPT end connections for straightforward installation into standard piping systems
- 25 Cv flow coefficient for reliable, high-capacity flow performance
- Three-way valve configuration supports mixing or diverting service
- Equal percentage flow characteristic ensures precise, stable control response
- Brass body construction for excellent corrosion resistance and long service life
- Chrome-plated brass ball provides smooth, durable operation and tight shutoff
- Brass stem for strength and resistance to wear in demanding HVAC environments
Construction & Design
The 599-10363 is built with a robust brass body that stands up to the rigors of commercial HVAC and building automation applications. The chrome-plated brass ball ensures a smooth seating surface and reliable sealing performance over extended service cycles. The brass stem adds structural integrity and minimizes the risk of corrosion-related failure, even in systems with varying water quality.
Applications
- Hydronic heating and cooling coil control
- Fan coil unit (FCU) and air handling unit (AHU) applications
- Building automation and direct digital control (DDC) systems
- Chilled water and hot water distribution systems
- Three-way mixing or diverting service in commercial HVAC
