Siemens Building Technology 270-03184 Valve Assembly
For high-performance hydronic control, the Siemens Building Technology 270-03184 Valve Assembly delivers a field-proven 2-way normally closed globe valve design for critical HVAC applications. This 3/4" NPT assembly is built on the Flowrite 599 series platform, featuring a durable 6.3 Cv equal percentage flow characteristic and bronze body construction with brass trim. Designed for precision, the equal percentage flow curve ensures linear heat output for efficient terminal unit management. The integrated 4-inch pneumatic actuator operates within a standard 10-15 PSI spring range, providing reliable normally closed fail-safe operation upon loss of control air. With an ANSI Class 250 pressure rating and Female x Female threaded connections, this valve and actuator assembly integrates seamlessly into any commercial control sequence requiring high closing force and 250°F maximum temperature tolerance.
- Precise Modulation: The equal percentage flow characteristic optimizes heat transfer in hydronic heating and cooling systems.
- Field Reliability: Rugged bronze body and brass internals provide long-term resistance to wear and debris in closed-loop systems.
- Fail-Safe Security: The 10-15 PSI spring transition ensures a secure normally closed position to prevent unintended flow during pneumatic signal failure.
- Simplified Installation: Standard 3/4" NPT ports allow for direct threading into existing piping without specialized adapters.
Common Questions
What is the maximum operating temperature for this assembly?
The Siemens 270-03184 is rated for fluid temperatures up to 250°F, making it suitable for both chilled water and low-pressure steam or hot water applications.
Can I use a higher air pressure signal than 15 PSI?
While the actuator starts moving at 10 PSI and is fully stroked at 15 PSI, the 4-inch pneumatic diaphragm can typically handle standard control air pressures up to 30 PSI, though consult the technical instructions for maximum actuator housing limits.
Does this valve require an external positioner?
No, for most standard terminal unit applications, the 10-15 PSI spring range provides sufficient control without a positioner, though one can be added if your application requires high precision or higher close-off pressures.
