Siemens Building Technology 270-03180 Valve Assembly
The Siemens Building Technology 270-03180 Valve Assembly is a high-performance 2-way normally closed pneumatic valve engineered for precise modulating control in demanding HVACR environments. Utilizing a 1/2 inch NPT threaded UNS CA 844 bronze body, this assembly is designed for hydronic systems and steam applications up to 15 psi. As part of the Flowrite 599 Series, it features an equal percentage flow characteristic with a 1.0 Cv rating, ensuring stable heat transfer and linear thermal output across the entire range of the stroke. The integrated 4-inch pneumatic actuator operates on a 10-15 psi spring range, providing a fail-safe closed position to protect downstream components during a loss of terminal air pressure.
This Siemens pneumatic globe valve is built with professional-grade internals, including a durable brass trim, a stainless steel stem, and EPDM O-ring packing. Designed to meet ANSI Class 250 pressure standards and ANSI Leakage Class IV (0.01% of Cv), it is an ideal replacement for aging terminal unit valves in air handlers or induction units. The direct-coupled universal bonnet allows for streamlined maintenance, and its high rangeability of >100:1 ensures accurate temperature regulation even under low-load conditions.
- Precise Flow Control: The equal percentage characteristic and 1.0 Cv rating provide superior modulation for hot water and chilled water systems.
- Fail-Safe Reliability: The normally closed configuration and rugged 10-15 psi pneumatic actuator ensure the valve returns to the safe position upon signal loss.
- Industrial Build Quality: Features a corrosion-resistant bronze valve body with a metal-to-metal seat for long-term service in high-pressure loops.
- High Temperature Compatibility: Rated for media temperatures ranging from 20°F to 250°F, making it versatile for both refrigeration and heating cycles.
Common Questions
What is the close-off pressure for the 270-03180 assembly?
This assembly is rated to provide tight close-off in alignment with ANSI Class IV leakage standards, typically handling high differential pressures common in terminal unit applications when driven by the 4-inch pneumatic actuator.
Is this valve suitable for steam service?
Yes, while primarily used for water and glycol solutions up to 50%, the brass trim and bronze body allow for saturated steam control up to 15 psi.
Can I install this valve in any orientation?
For optimal performance, it is recommended to install the valve with the actuator in the upright vertical position; however, it can be mounted horizontally if necessary. Avoid mounting the actuator below the horizontal plane to prevent moisture buildup in the diaphragm.
