Siemens Building Technology 257-02070B Valve Assembly
For high-performance hydronic system management, the Siemens Building Technology 257-02070B Valve Assembly provides unmatched precision in temperature control applications. This assembly features the Siemens Powermite 599 MT Series 3-way mixing valve body, constructed from professional-grade forged brass with reliable brass trim. Contractors specify this unit for its robust ANSI Class 250 rating, ensuring long-term durability in high-static environments. With a 3/4" NPT connection and a 6.3 Cv linear flow rate, it facilitates smooth modulating control for hot or chilled water systems.
The system is powered by a 2-inch pneumatic valve actuator utilizing a 3-8 PSI spring range. This spring return pneumatic actuator is engineered for a 7/32-inch stroke, providing the mechanical force necessary for tight shut-off and accurate mixing. The linear flow characteristic is essential for maintaining stability in terminal unit applications such as convectors or fan coil units. Designed for ease of field installation, the compact footprint allows for integration into tight mechanical spaces without compromising accessibility for routine maintenance.
Key Benefits- Durable Construction: The forged brass body and brass trim resist corrosion in standard hydronic loops.
- Precise Modulation: The linear flow characteristic ensures predictable performance across the entire 3-8 PSI spring range.
- High Pressure Rating: Rated for ANSI Class 250, making it suitable for demanding commercial HVACR systems.
- Efficient Installation: Integrated assembly with 3/4" NPT threads allows for direct-coupled threading into existing pipework.
Is the 257-02070B suitable for steam applications?
While the 599 MT series handles high temperatures, this specific 3-way mixing assembly is optimized for water and glycol solutions up to 50%. Always check trim compatibility for specific steam pressure requirements.
Can I use this for diverting applications?
The 257-02070B is specifically piped and ported as a mixing valve. Using it in a diverting configuration may lead to noise or premature seat wear due to flow direction issues.
What is the maximum medium temperature for this assembly?
This Siemens pneumatic valve assembly is designed to handle fluid temperatures ranging from 35°F to 250°F.
