The Siemens 256-02041A is a 1/2-inch two-way normally open globe valve designed for commercial and industrial HVAC applications. This valve features female-by-female (FxF) threaded connections and operates with a spring range of 10-15 PSI, making it ideal for precise control of water, steam, or other compatible fluids in heating and cooling systems.

Key Features:

• Two-way normally open (NO) configuration allows flow when de-energized
• 1/2-inch FxF threaded connections for easy installation
• 10-15 PSI spring range for reliable pneumatic actuation
• Durable brass construction for long service life
• Suitable for use with pneumatic actuators in building automation systems
• Compatible with Siemens HVAC control systems and other standard pneumatic controls

This valve is commonly used in zone control applications, mixing circuits, and other HVAC system configurations where failsafe flow-through operation is required during power or control signal loss.
