Siemens Building Technology 599-03185 Flowrite 1" 2-Way Control Valve Body Normally Closed

The Siemens Building Technology 599-03185 is a Flowrite 1-inch 2-way globe valve body designed for precision flow control in HVAC and building automation systems. This normally closed (NC) valve features a 10 Cv flow coefficient and equal percentage flow characteristic, making it ideal for accurate modulation of water and steam in heating and cooling applications.

Key Features:

• 1-inch NPT female x female threaded connections for easy installation
• Brass trim construction ensures durability and corrosion resistance
• ANSI Class 250 pressure rating with 360 PSI close-off pressure capability
• Equal percentage flow characteristic for precise control
• Operating temperature range: 35°F to 250°F (-2°C to 121°C)
• Greater than 100:1 rangeability for excellent turndown performance
• Globe-style design with direct-coupled bonnet
• Class IV leakage rating (0.01% of Cv) for tight shut-off
• Compatible with pneumatic or electronic actuators with 3/4-inch stroke

This valve body requires a separate actuator for operation and is fully serviceable for long-term reliability. Commonly used in air handling units, fan coil units, heat exchangers, and other commercial HVAC equipment where precise flow control is essential.
