Siemens 241-00210 1/2" 120V 2-Way NPT Control Valve CV 1.0 Normally Open

The Siemens 241-00210 is a 1/2-inch normally open control valve designed for precise fluid flow control in HVAC and building automation systems. This 2-way valve features a 1.0 Cv (flow coefficient) rating and 120V operation, making it ideal for small to medium-sized hydronic applications.

Key Features:

• 1/2-inch NPT threaded connections for easy installation
• 120V 2-wire actuator with spring return fail-safe positioning
• Normally open configuration (closes on power application)
• 1.0 Cv flow coefficient for accurate flow control
• Compatible with Siemens building automation systems
• Compact design suitable for tight installations
• Spring return actuator provides fail-safe operation during power loss

This valve assembly is commonly used in heating and cooling coil applications, zone control systems, and other hydronic circuits where reliable on/off or modulating control is required. The normally open design ensures flow during power failure, making it suitable for safety-critical applications.
