Siemens Building Technology 259-02034 Valve Assembly
For high-performance terminal unit control, the Siemens 259-02034 Globe Valve Assembly provides precise hydronic regulation in a compact footprint. This 2-way normally open valve features a 1/2 inch NPT female-to-female connection, making it an ideal drop-in solution for fan coil units, baseboard radiation, and reheat coils. The assembly is built around a heavy-duty forged brass body with a durable brass trim, ensuring reliable service in water and water-glycol solutions up to 50% concentration.
The unit is equipped with a non-spring return floating actuator (SSC81U) that operates on 24Vac power. With a 1.0 Cv equal percentage flow characteristic, this Powermite 599 MT Series assembly delivers linear heat output and stable temperature control. It is rated for ANSI Leakage Class IV, providing a tight close-off pressure of up to 120 psi. The 3-position floating control signal allows for incremental positioning, while the "fail in-place" logic ensures the valve remains in its last position during a power loss event, preventing sudden system fluctuations.
- Precise Flow Control: 1.0 Cv rating with equal percentage flow ensures accurate heat transfer in terminal unit applications.
- Rugged Construction: Forged brass body and brass trim offer maximum resistance to corrosion and mechanical wear.
- Installation Flexibility: Compact design with 1/2" NPT threading allows for easy mounting in tight mechanical spaces.
- High Close-Off: Rated for 120 psi close-off pressure to prevent leakage in high-head system environments.
- Efficient Actuation: Low power consumption (0.8 VA) 24V electronic actuator simplifies wiring for multi-zone projects.
Common Questions
What is the maximum fluid temperature this assembly can handle?
This Siemens assembly is rated for media temperatures ranging from 35°F to 250°F, making it suitable for both chilled water and low-pressure steam applications under 15 psi.
Is this a fail-safe or non-fail-safe actuator?
The 259-02034 uses a non-spring return (NSR) actuator, meaning it will fail in its last physical position if power is lost, rather than returning to a fully open or closed state.
Can I use this for modulating control?
This specific model uses a 3-position floating control signal (increase/decrease). It is designed for systems that use floating point controllers rather than 0-10VDC or 4-20mA proportional signals.
