Siemens Building Technology 283-03184 3/4" Normally Closed Globe Valve Assembly 6.3 Cv with 8" Pneumatic Actuator and Positioner

The Siemens Building Technology 283-03184 is a complete 2-way globe valve assembly designed for precise fluid flow control in commercial HVAC systems. This normally closed valve features a 3/4-inch female x female NPT connection with a 6.3 Cv flow coefficient, making it ideal for hot or chilled water applications in zones with radiators, fan coil units, and cooling systems.

Key Features:

• 2-way normally closed configuration with equal percentage flow characteristic
• 3/4-inch NPT female x female threaded end connections
• 6.3 Cv flow coefficient for controlled water flow
• ANSI Class 250 pressure rating with brass trim construction
• 8-inch spring return pneumatic actuator with factory-mounted positioner
• Positioner enables precise proportional control with 3-15 psi air signal input
• Flowrite 599 Series valve body for reliable performance

This valve assembly combines the 599-03184 valve body with an 8-inch pneumatic actuator featuring a built-in positioner for accurate positioning control. The positioner allows for modulating control based on pneumatic input signals, ensuring efficient operation of heating and cooling systems. The brass trim construction provides excellent durability and corrosion resistance for water service applications.
