Siemens Building Technology 599-10303 Valve
This Siemens 599-10303 is a 1/2-inch, two-way ball valve designed for precision fluid control in HVAC systems. Engineered with a 1.6 Cv and equal percentage flow characteristic, it ensures linear heat output when used in chilled water or hot water applications, including 50% glycol mixtures. The brass body is reinforced with a chrome-plated brass ball and brass stem, providing a 200 psi close-off rating and meeting ANSI Class IV leakage standards. This 1/4-turn rotary valve is optimized for coupling with OpenAir actuators, featuring a universal mounting plate and blow-out proof stem to facilitate reliable proportional control in fan coil units and unit conditioners. Technicians will appreciate the 1/2" NPT connection and the 35°F to 250°F media temperature range for versatile field installation.
Key Benefits- Precise Flow Control: The equal percentage characteristic delivers stable temperature regulation in hydronic systems.
- Durable Construction: Forged brass body with chrome-plated ball prevents scale buildup and ensures long-term reliability.
- Universal Compatibility: Standardized mounting facilitates quick pairing with GDE, GLB, GMA, and GQD actuators.
- High Close-Off: Rated at 200 psi to prevent ghost flows and ensure zero-leakage performance in high-head applications.
Is the 599-10303 suitable for steam?
No, this specific model is designed for water and glycol solutions up to 250°F. For steam applications, a stainless steel trim or steam-rated assembly is required.
Can I install this valve in any orientation?
While the valve can be rotated in 90-degree increments, it must be installed with the actuator above or to the side of the piping to prevent condensation from entering the electronics.
Does this valve come with an actuator?
This part number refers to the valve body only. Actuators must be selected separately based on control signal and fail-safe requirements.
