Siemens Building Technology 283-06051 Normally Closed Globe Valve Assembly with Pneumatic Actuator - 3-Inch 2-Way 8-Inch

The Siemens Building Technology 283-06051 is a complete pneumatic valve actuator assembly designed for HVAC control applications. This 2-way normally closed globe valve features a 3-inch flanged connection with 125 PSI pressure rating, making it suitable for hot water, chilled water, and hydronic heating and cooling systems.

Key Features:

• 3-inch flanged globe valve body with 125 PSI pressure rating
• Stainless steel trim for durability and corrosion resistance
• 8-inch pneumatic actuator with spring return fail-safe operation
• Normally closed (NC) configuration - valve closes on air pressure loss
• 3-10 PSI control signal range for proportional control
• Linear flow characteristic for precise temperature control
• Flanged connections for easy installation and maintenance

This valve assembly is ideal for commercial HVAC applications including boiler systems, chilled water distribution, fan coil units, heat exchangers, and zone control applications. The pneumatic actuator provides reliable modulating or two-position control based on controller output signal.
