Siemens Building Technology 283-06170 Flowrite 3-Way Mixing Valve Assembly 2-1/2" Flanged 63Cv Bronze Trim 8" Pneumatic Actuator

The Siemens Building Technology 283-06170 is a Flowrite 599 Series three-way pneumatic valve actuator assembly designed for commercial HVAC hydronic control applications. This complete factory-assembled unit pairs a 2-1/2-inch flanged globe valve body with an 8-inch pneumatic actuator and an integrated factory-mounted positioner for precise, reliable flow control.

This valve assembly is configured for three-way mixing service, combining two inlet streams into a single outlet to regulate system water temperature. The bronze trim construction and ANSI Class 250 pressure rating make it well suited for hot and chilled water systems as well as glycol solutions.

Key Features:

• 3-way, mixing action with equal percentage/linear flow characteristic
• 2-1/2-inch flanged end connections (ANSI Class 250)
• 63 Cv flow coefficient for high-capacity hydronic applications
• 8-inch pneumatic actuator with factory-mounted positioner
• 5 psi control span for precise modulating control
• Bronze trim with stainless steel stem
• 3/4-inch valve stroke
• Compatible with water and glycol solutions up to 50%
• Operating temperature range: 20°F to 250°F (-7°C to 120°C)
• Spring-return fail-safe operation

The Flowrite 599 Series is a proven platform for commercial building automation and control systems. The complete valve-actuator assembly ships factory-assembled and tested, reducing installation time and ensuring proper component matching. Service flanges are sold separately.
