Belimo Z2050QSFCQKB24SRLL ZoneTight 1/2" 2-Way Modulating Valve with Electronic Fail-Safe Actuator 24V

The Belimo Z2050QSFCQKB24SRLL is a ZoneTight pressure-independent characterized control valve (PICCV) designed for precision hydronic zone control in HVAC applications. This compact 1/2" two-way valve features a 1.4 Cv flow coefficient and sweat (solder) copper connections for reliable installation in hot water, chilled water, and glycol systems.

Key Features:

• ZoneTight pressure-independent technology maintains precise flow control regardless of system pressure fluctuations
• Electronic fail-safe actuator with spring return functionality ensures fail-safe positioning during power loss
• Modulating control with 2-10 VDC input signal for precise temperature control
• 24V AC/DC power supply for flexible integration with building automation systems
• 1.4 Cv flow coefficient suitable for small zone applications
• Sweat copper connections for secure, leak-free installation
• Compact design ideal for space-constrained installations
• Equal percentage flow characteristic for optimal control performance

This valve assembly combines Belimo's reliable rotary actuator technology with a precision-engineered ball valve body, providing long-lasting performance in commercial and residential HVAC systems. The pressure-independent design eliminates the need for separate balancing valves, simplifying system design and reducing installation costs.
