Siemens Building Technology 599-03185 Valve

The Siemens Building Technology 599-03185 is a professional-grade two-way normally closed globe valve engineered for precise control in demanding hydronic and steam applications. Designed with a robust UNS CA 844 bronze body and durable brass trim, this 1-inch NPT valve body features a 10 Cv flow coefficient and equal percentage flow characteristics, ensuring stable modulation and high rangeability exceeding 100:1. Built to meet ANSI Class 250 standards, it handles medium temperatures from 20°F to 250°F, making it a reliable solution for chilled water, hot water, and saturated steam systems. The direct-coupled universal bonnet simplifies field integration with Siemens Flowrite actuators, while the cartridge-type packing allows for straightforward maintenance without pulling the valve from the line. With an ANSI Leakage Class IV rating, this globe valve provides tight shut-off to maintain system efficiency and prevent energy loss.

Key Benefits

• High-Performance Modulation: The equal percentage flow design ensures linear thermal output for superior temperature control.
• Durable Construction: Features brass trim and an EPDM O-ring packing suited for 50% water-glycol solutions and steam.
• Standardized Compatibility: Compatible with any 3/4-inch stroke Siemens pneumatic or electronic actuator for versatile HVACR setups.
• Field Serviceable: The cartridge-type packing design reduces downtime during routine mechanical inspections.
• Pressure Integrity: Rated for ANSI Class 250, providing reliable performance under significant static and dynamic pressures.

Common Questions

What is the fail-safe position for the 599-03185 valve?
This is a normally closed (NC) valve body. The final assembly's fail direction depends on your specific linear actuator, but the valve naturally returns to the closed position when there is no upward force on the stem.

Can this valve be used for steam applications?
Yes, the Siemens 599-03185 is rated for saturated steam up to 15 psi and 250°F. For higher temperature or pressure steam requirements, ensure your actuator and packing selection are rated for the specific load.

In what orientation should I install this globe valve?
For optimal service life, install with the actuator in the upright vertical position. It can be mounted up to 90 degrees from vertical, but should never be installed with the actuator pointing below the horizontal plane to prevent moisture from damaging the electronics or pneumatic seal.
