Description
Siemens Building Technology 599-05990 Globe Valve Overview
The Siemens Building Technology 599-05990 is a 2-way, normally closed globe valve engineered for precision flow control in commercial HVAC and hydronic systems. Featuring a 2-1/2″ flanged connection and a high-capacity 63 Cv flow coefficient, this valve delivers reliable, repeatable performance in demanding building automation and mechanical system applications.
Key Features
- 2-Way, normally closed (NC) configuration for fail-safe operation
- 2-1/2″ flanged end connections for secure, leak-resistant installation
- 63 Cv flow coefficient for high-volume flow capacity
- Equal percentage flow characteristic for precise, linear control response
- ANSI Class 125 pressure rating for compatibility with standard hydronic and steam systems
- Cast iron body construction for durability and long service life
- Bronze trim for corrosion resistance and reliable sealing performance
Construction & Design
The 599-05990 globe valve body is constructed from ANSI Class 125 cast iron, providing robust mechanical strength suited for commercial and light industrial HVAC applications. The bronze trim components offer excellent resistance to corrosion and wear, ensuring long-term valve integrity even in demanding hydronic environments. The globe-style body design promotes smooth, turbulence-minimizing flow paths that extend service life and reduce pressure drop.
Flow Characteristics
This valve utilizes an equal percentage flow characteristic, meaning that equal increments of valve stem travel produce equal percentage changes in flow rate. This characteristic is ideal for applications where the valve controls a significant portion of the system pressure drop, providing stable and accurate modulating control across the full operating range.
Applications
- Commercial HVAC heating and cooling coil control
- Hydronic heating and chilled water systems
- Building automation system (BAS) valve control
- Air handling unit (AHU) hot water and chilled water coils
- Fan coil unit and terminal unit flow regulation
