Siemens Building Technology 274-03054 Valve Assembly
The Siemens Building Technology 274-03054 Valve Assembly is a precision-engineered control solution for commercial HVACR hydronic systems. This factory-assembled 2-way normally open valve features a 1/2" NPT connection and a 1.0 Cv rating, optimized for low-flow modulation in fan coil units, air handlers, and reheat coils. The bronze body (UNS CA 844) is paired with stainless steel trim and high-temperature packing, enabling the assembly to handle medium temperatures up to 337°F (169°C) and saturated steam applications.
Driven by a 24Vac electro-hydraulic actuator, this assembly offers a proportional control signal (0-10Vdc or 4-20mA) for seamless integration with building automation systems (BAS). The spring-return functionality ensures a fail-safe open position, maintaining flow continuity and system protection during power loss. With an ANSI Class 250 pressure rating and a linear flow characteristic, this Flowrite 599 series valve delivers stable, predictable performance in demanding mechanical environments.
Key Benefits:
- 1/2" NPT with 1.0 Cv: Ideal for precise modulation in low-flow hydronic circuits.
- Fail-Safe Normally Open: Integrated spring return ensures flow remains open during power interruptions.
- High-Temperature Durability: Stainless steel trim and specialized packing support saturated steam and water up to 337°F.
- Universal Compatibility: Accepts standard 0-10Vdc and 4-20mA signals for direct BAS interface.
- Industrial Build: ANSI 250 rated bronze body with stainless steel stem and single-seat metal-to-metal seal.
Common Questions:
What is the default fail position for this assembly?
This is a normally open (NO) assembly; the internal spring returns the valve to the fully open position if the 24Vac power signal is lost.
Can this valve be used for steam service?
Yes, the 274-03054 is rated for saturated steam and features high-temperature packing specifically for these applications.
What control signals does the electronic actuator support?
The proprotional actuator is compatible with standard 0-10Vdc or 4-20mA DC control signals for precise positioning.
