Siemens Building Technology 599-06171 Flowrite VF 599 Series 3-Inch Flanged 3-Way Globe Valve, 100 Cv, Bronze Trim, ANSI Class 250

The Siemens Flowrite VF 599 Series 599-06171 is a 3-inch flanged, iron body, 3-way globe valve with bronze trim, rated to ANSI Class 250. Part of Siemens' well-established Flowrite VF 599 Series, this valve body is designed to work with either pneumatic or electronic actuators, offering flexible integration into a wide range of HVAC building automation and control systems.

With a flow coefficient (Cv) of 100 and a 3/4-inch (20 mm) stroke, this valve delivers precise flow control for commercial and industrial hydronic applications. The flanged iron body construction and ANSI Class 250 pressure rating make it well-suited for demanding heating and cooling plant environments.

Key Features:

• Valve Type: 3-way mixing, globe style
• Line Size: 3 inch (80 mm)
• Cv (Flow Coefficient): 100 (Kvs 85)
• Stroke: 3/4 inch (20 mm)
• Pressure Rating: ANSI Class 250
• Connection Type: Flanged — flange face-to-face dimensions meet ISA 75.03 standards
• Body Material: Iron
• Trim Material: Bronze
• Actuator Compatibility: Pneumatic or electronic actuator (sold separately)
