Siemens Building Technology 599-10305S Valve
The Siemens Building Technology 599-10305S is a high-performance 2-way ball control valve engineered for critical flow regulation within HVAC hydronic systems. Featuring a 4.0 Cv flow coefficient and an equal percentage flow characteristic, this valve ensures linear heat transfer and precise modulation in both chilled water and hot water loops. The 1/2" NPT threaded connection allows for standard integration into existing piping, while the forged brass body and stainless steel ball and stem provide superior resistance to corrosion and scaling in high-duty cycles. As part of the Siemens OpenAir series, this 1/2 inch HVAC ball valve is optimized for low-torque operation, extending the service life of compatible non-spring return actuators and spring return electronic actuators. Its blow-out proof stem design and chrome-plated or stainless internals make it a reliable choice for contractors managing building automation systems that require tight shut-off and consistent performance.
Key Benefits:
- 4.0 Cv rating provides optimized flow control for terminal units and small branch lines.
- Built with a stainless steel ball and stem to withstand aggressive fluid conditions and prevent sticking.
- Features equal percentage flow characteristics for stable temperature control in modulating applications.
- Compatible with a wide range of Siemens rotary actuators for flexible building automation system integration.
- Forged brass body construction provides a 600 psi static pressure rating for robust system reliability.
Common Questions:
- What is the primary application for the 599-10305S? It is designed for modulating or two-position control of hot or chilled water in air handling units, re-heat coils, and fan coil units.
- Which actuators are compatible with this valve? This valve integrates with Siemens GDE/GLB series and GMA/GCA series actuators using specific mounting kits.
- Can this valve be used for steam applications? No, this specific model is rated for hydronic systems (water and water-glycol mixtures) rather than high-pressure steam service.
