Siemens Building Technology 599-02038 Valve
The Siemens Building Technology 599-02038 is a high-performance 2-way normally open globe valve body engineered for precise terminal unit control. Constructed with a heavy-duty forged brass body and brass trim, this 1/2-inch NPT valve is a staple for contractors managing hot water, chilled water, or 50% glycol solutions. With a 2.5 Cv flow coefficient and a modified equal percentage flow characteristic, it provides stable modulation and high rangeability (exceeding 100:1) to prevent hunting in HVAC zone valve applications. Classified as ANSI Class 250, it handles medium temperatures from 35°F to 250°F and maintains an ANSI Leakage Class IV rating. The direct-coupled universal bonnet allows for seamless installation with Siemens Powermite MT Series electronic actuators or pneumatic equivalents without the need for specialized tools. This Siemens 599-02038 is the reliable choice for maintaining flow efficiency in fan coils, baseboard radiation, and reheat coils.
Key Benefits- Precise Flow Control: The modified equal percentage design ensures accurate heat transfer and system stability.
- Contractor-Friendly Installation: Features a direct-coupled universal bonnet for rapid, tool-free actuator mounting.
- Durable Construction: Forged brass ASTM B283 body resists de-zincification and stands up to high-pressure ANSI 250 environments.
- Versatile Compatibility: Integrates easily with the Siemens 599-01088 pneumatic actuator or SAS/SSC electronic actuators.
What is the close-off pressure for this valve?
When paired with the correct MT Series actuator, this valve body typically supports a close-off pressure up to 25 psi, depending on the specific actuator torque and spring range.
Can I use this valve for steam applications?
While the 599-02038 features brass trim optimized for water and glycol, stainless steel trim variants within the Powermite 599 series are recommended for low-pressure steam up to 15 psi.
What is the stroke length required for the actuator?
This valve is designed for a 7/32-inch (5.5 mm) stroke, making it compatible with the entire line of Siemens SFA, SFP, SSA, and SSP actuators.
