Siemens Building Technology 599-10309 Valve

The Siemens Building Technology 599-10309 Valve is a professional-grade 3/4 inch NPT ball valve engineered for precise equal percentage flow control in demanding HVACR applications. This two-way control valve features a robust forged brass body rated at 600 WOG/ANSI 250, ensuring long-term reliability in high-pressure hydronic systems. With a 10 Cv rating, it is ideal for managing fluid flow through fan coil units, reheat coils, and unit conditioners. The internal chrome-plated brass ball and brass stem provide smooth operation and high resistance to wear from debris. This model includes EPDM O-rings and glass-filled PTFE seals, allowing it to handle media temperatures from 35°F to 250°F and up to 50% water-glycol solutions. The blow-out proof stem and 200 psi close-off pressure rating ensure safe performance and low leakage rates (ANSI Class IV), making this Siemens 599-10309 a standard choice for contractors requiring dependable HVAC valve components.

• Universal Compatibility: The integrated mounting plate supports seamless installation with Siemens OpenAir actuators for automated control.
• Precise Modulation: The equal percentage flow characteristic minimizes hunting and improves system stability during partial load conditions.
• Manual Override: A dedicated operating handle allows for manual positioning in the event of a power failure or during initial system commissioning.
• Thermal Protection: Designed with standoffs that create a thermal barrier to protect the actuator from extreme media temperatures.
• Field Versatility: The 3/4-inch FNPT connections allow for direct replacement in existing piping layouts without complex modifications.

• Is this valve compatible with glycol? Yes, the Siemens 599-10309 is rated for use with up to 50% water-glycol solutions, common in chilled water loops.
• What is the maximum static pressure? This valve body is designed for a maximum static pressure of 360 psi.
• Can I use this for steam applications? No, this specific brass trim model is designed for hot and chilled water; refer to stainless steel trim models for more aggressive media.
