Siemens Building Technology 274-03200 Valve Assembly
The Siemens Building Technology 274-03200 is an industrial-grade 3-way mixing valve assembly engineered for high-demand hydronic applications. This high-performance flowrite 599 series valve features a 1/2-inch NPT connection and is calibrated for a 2.5 Cv flow coefficient, providing precise water or glycol temperature control in HVAC systems. Built with a rugged UNS CA 844 bronze body and durable brass trim, the assembly is rated for ANSI Class 250 pressure requirements. The integrated spring return modulating actuator accepts standard 0-10Vdc or 4-20mA control signals, ensuring fail-safe positioning in the event of power loss. With a 3/4-inch stroke and equal percentage/linear flow characteristics, this Siemens 3-port valve assembly offers superior rangeability for tight-tolerance climate management. This assembly for contractors and technicians is specifically designed for 24Vac operation, making it compatible with most building automation systems.
Key Benefits- Fail-Safe Reliability: Integrated spring return normally-closed functionality ensures the system reaches a safe state during power interruptions.
- Precision Control: Utilizes a modulating electro-hydraulic actuator to provide smooth, incremental adjustments for critical mixing processes.
- Rugged Construction: Featuring a corrosion-resistant bronze body and EPDM O-ring packing suited for media temperatures up to 250°F.
- Flexible Signal Compatibility: Supports dual-mode analog control input (0-10Vdc or 4-20mA) for seamless integration with universal DDC controllers.
What is the maximum close-off pressure for this assembly?
The 274-03200 is rated for a maximum close-off pressure of up to 200-250 psi depending on the specific pump head, making it reliable for high-static building loops.
Can this be used for diverting applications?
While designed primarily as a 3-way mixing valve, the internal 599 series globe structure is optimized for mixing two inlet flows into one outlet. For diverting applications, verify port orientation and flow direction carefully.
What media is compatible with this bronze valve?
This unit is designed for use with water or water-glycol solutions containing up to 50% antifreeze, provided the temperatures remain within the 20°F to 250°F range.
