Siemens Building Technology 283-03168 Flowrite 2-Way Globe Valve Assembly 1.25" 16 Cv with Pneumatic Actuator

The Siemens Building Technology 283-03168 is a Flowrite 599 Series valve assembly designed for commercial and industrial HVAC applications requiring precise flow control of water, glycol solutions up to 50%, and saturated steam. This complete assembly features an 8-inch pneumatic actuator with factory-mounted positioner for accurate modulating control.

Valve Specifications:

• 2-way, normally open (N/O) globe valve design
• 1-1/4 inch (32mm) line size with female NPT x female NPT connections
• 16 Cv flow coefficient for optimal capacity
• Equal percentage flow characteristic for precise control
• Bronze trim construction for durability and corrosion resistance
• ANSI Class 250 rated body
• 93 psi rated close-off pressure
• Maximum operating temperature: 250°F

Actuator Features:

• 8-inch spring return pneumatic actuator
• Factory-mounted positioner with 5 psi control span
• NEMA 1 enclosure rating
• Fail-safe normally open position for safety
• 3-60 psi control signal range

This valve assembly is ideal for heating, cooling, and process control applications where reliable, modulating control of fluid flow is required. The pre-assembled design ensures proper valve-actuator matching and reduces installation time.
