Siemens Building Technology 274-03080 Control Valve Assembly
The Siemens 274-03080 Control Valve Assembly is a heavy-duty solution for precise hydronic flow control in commercial HVAC systems. This 2-way normally closed modulating valve features a 2-inch NPT connection and is engineered with a 40 Cv linear flow characteristic to ensure stable regulation in air handling units and heat exchangers. Designed for seamless integration, the Siemens actuator accepts both 0-10 VDC and 4-20 mA control signals, operating on standard 24 VAC power. The bronze body construction paired with stainless steel trim provides the necessary ruggedness for closed-loop chilled water and heating applications. Equipped with a spring return modulating actuator, the assembly ensures a reliable fail-safe position during power loss, protecting critical equipment. Whether managing variable flow loads or maintaining tight temperature setpoints, this Siemens valve and actuator combination delivers the technical performance required by professional mechanical contractors and building automation specialists.
Key Benefits:- Linear Flow Characteristic: Optimized 40 Cv rating provides ultra-stable modulation for precise temperature maintenance in hydronic loops.
- Universal Signal Compatibility: Supports standard 0-10 VDC or 4-20 mA inputs for easy integration with modern Building Automation Systems (BAS).
- Industrial Build Quality: High-grade bronze valve body and stainless steel trim resist corrosion and handle high-pressure differentials.
- Fail-Safe Logic: Integrated spring return mechanism ensures the valve returns to a normally closed position upon loss of power.
- Simplified Installation: 2-inch NPT threaded connections allow for standard piping integration without specialized welding or flange kits.
What is the fail-safe orientation of this Siemens assembly?
This is a normally closed (NC) assembly. The internal spring return mechanism automatically drives the valve to the closed position if control power is interrupted.
Can I use this valve for both heating and cooling applications?
Yes, this assembly is designed for use in chilled water and hot water systems, provided the media is compatible with bronze and stainless steel internals.
Are both voltage and current control signals supported out of the box?
The modulating actuator is field-configurable to accept either a 0-10 VDC or 4-20 mA signal, allowing for flexible commissioning depending on your controller output.
