The valve incorporates an equal percentage characteristic with a TEFZEL® characterized disc to maintain stable control across varying load conditions. Its integrated ARX24-3-T N4 actuator provides non fail-safe operation with on/off and floating point control, suitable for robust HVAC control strategies. Factory assembly ensures precise valve-to-actuator alignment, reduces installation effort, and supports long-term reliability in harsh indoor or outdoor environments. Key Features Two Way Characterized Valve Design: Provides precise hydronic flow control with an equal percentage characteristic for consistent system performance. Non Spring Return Actuator: Powered positioning without fail-safe spring action supports applications where return on power loss is not required. On Off And Floating Point Control: Enables simple, reliable control methods commonly used in large hydronic systems. Rugged NEMA 4X Enclosure: IP66/67 rated actuator housing protects against moisture, dust, and corrosion in demanding installations. Zero Leakage Construction: Precision valve components ensure tight shutoff and reliable flow isolation. Electronic Overload Protection: Protects actuator components throughout the full rotation range to extend service life. Manual Override Access: Allows local valve positioning during commissioning or maintenance without external power. The B261+ARX24-3-T N4 delivers the reliability and precision required for dependable two-way hydronic flow control in challenging HVAC applications.
