Siemens Building Technology 274-03184 Valve Assembly
The Siemens Building Technology 274-03184 Valve Assembly is a high-performance 2-way normally closed valve engineered for precision in demanding HVACR applications. Built with a rugged bronze body and durable brass trim, this 3/4 inch NPT assembly is part of the Flowrite 599 Series. It features an equal percentage flow characteristic that ensures stable control across its entire operating range, making it a reliable choice for hydronic systems. The integrated spring return modulating actuator is powered by 24Vac and supports both 0-10Vdc and 4-20mA control signals, providing field-selectable flexibility for modern building automation interfaces. With a 6.3 Cv rating and ANSI Class 250 pressure compliance, this assembly handles medium temperatures from 20 to 250 degrees Fahrenheit, including saturated steam and water/glycol mixtures. The electro-hydraulic spring return fail-safe ensures the valve closes securely upon power loss, protecting critical equipment from overflow or thermal issues.
Key Benefits:- Precise Modulation: Advanced equal percentage flow delivery minimizes hunting in control loops.
- Fail-Safe Security: Reliable spring return mechanical fail-safe for normally closed protection.
- Hybrid Control: Technical compatibility with both 4-20mA and 0-10Vdc proportional signals.
- Durable Construction: Heavy-duty UNS CA 844 bronze body with stainless steel stem for long-cycle life.
- High Pressure Rating: ANSI Class 250 certification allows for use in high-rise and industrial hydronic loops.
What is the fail-safe position of this assembly?
This is a normally closed assembly, meaning the spring return actuator will drive the valve to a tight shut-off position if 24Vac power is lost.
Can I use this for steam applications?
Yes, the Siemens 274-03184 is rated for saturated steam and water with anti-freeze, provided the medium temperature remains within the 20 to 250 degree Fahrenheit operating window.
Does this require specific tools for installation?
The Flowrite 599 series features a direct-coupled universal bonnet design, which simplifies mounting the actuator to the valve body without complex linkage adjustments.
