Belimo WAF Valve Linkage

The Belimo WAF Valve Linkage is a professional-grade mechanical interface designed to bridge AF and NF series spring-return actuators with B2 and B3 Series characterized control valves. Engineered for precision in demanding HVACR environments, this actuator valve linkage ensures a secure, slip-free connection between the motor drive and the valve stem, maintaining the equal percentage flow characteristic required for stable hydronic control. As a veteran-preferred HVAC replacement part, the WAF series is built to handle the high-torque output of AFB and NFB actuators, ranging from 1/2" to 3" valve body sizes. By utilizing a direct-coupled mounting configuration, this Belimo accessory eliminates the hysteresis often found in field-fabricated linkages, ensuring that Building Automation Systems (BAS) receive accurate feedback and command responses. Whether you are performing a retrofit or a new installation, this linkage provides the structural integrity needed for 2-way and 3-way ball valve applications involving hot or chilled water and glycol solutions up to 60%.

• Durable Construction: High-strength materials designed to withstand continuous 95-degree rotation and high close-off pressures.
• Precise Alignment: Engineered specifically for Belimo AF/NF actuators to prevent stem binding and premature seal wear.
• Versatile Compatibility: Seamlessly integrates with B2 Series 2-way and B3 Series 3-way ball valves across multiple Cv ratings.
• Field Reliability: Simplifies the installation process for contractors, ensuring repeatable performance in proportional and floating control setups.

• Which actuators are compatible with the WAF linkage? This linkage is designed specifically for the Belimo AF and NF actuator series, including the AFB and NFB models.
• Can this be used for steam applications? The WAF is rated for hot and chilled water or glycol solutions; always verify the valve body temperature limits for your specific media.
• Does this include the actuator or the valve? No, the WAF is the mechanical linkage assembly only; actuators and valve bodies must be sourced separately based on your torque and flow requirements.
