Siemens Building Technology 599-01121 Valve

The Siemens Building Technology 599-01121 Valve is a 1/2 inch globe valve body engineered for high-precision flow regulation in terminal units and zone control systems. Designed with a normally open configuration and a 1.6 Cv capacity, this 2-way valve utilizes a modified equal percentage flow characteristic to ensure consistent temperature stabilization across various load demands. The forged brass body and brass trim provide a rugged foundation capable of managing hot or chilled water and water-glycol solutions up to 50% concentration. This Powermite 599 series component is rated for ANSI Class 250, offering a reliable choice for contractors handling high-pressure HVAC applications where tight shut-off and durable NPT threaded connections are required. The direct-coupled universal bonnet facilitates seamless field integration with compatible Siemens electronic or pneumatic actuators, streamlining installation in tight mechanical closets and fan coil units.

• Precise Modulation: Features a modified equal percentage flow curve for superior control stability in water-based HVAC systems.
• Industrial Durability: Construction includes a forged brass body and brass trim to resist de-zincification and mechanical wear.
• Broad Compatibility: The direct-coupled universal bonnet allows for tool-free actuator mounting, reducing labor time during field retrofits.
• High Pressure Rating: Built to ANSI Class 250 standards, suitable for demanding commercial piping environments.
• Reliable Scaling: The 1.6 Cv rating is optimized for terminal equipment like reheat coils and radiation zones.

What is the maximum media temperature for the 599-01121?
This valve is designed to handle media temperatures ranging from 34°F to 250°F, making it suitable for both chilled water and low-pressure heating applications.

Can this valve be field-converted to normally closed?
The baseline action of the 599-01121 is normally open; however, the final operating state is typically determined by the specific actuator selection and its internal spring-return configuration.

What actuators are compatible with the Siemens 599-01121?
It is specifically designed for use with the Siemens Powermite 599 Series electronic or pneumatic actuators requiring a 7/32-inch stroke and delivering at least 45 lb (200 N) of force.
