Johnson Controls V-9999-670 Bonnet Adaptor

The Johnson Controls V-9999-670 Bonnet Adaptor is a critical hardware component engineered for technicians performing field retrofits on HVAC control valves. This high-precision adapter facilitates the seamless actuator mounting of VA-715X Series electric actuators onto VT Series valve bodies specifically equipped with threaded stems. Built to withstand rigorous mechanical cycling, the V-9999-670 ensures a stable interface between the motor-driven actuator and the valve bonnet, maintaining axial alignment and optimal stroke transfer for precise fluid flow modulation.

Professional contractors utilize this valve bonnet kit to upgrade legacy terminal unit systems or replace failed components without replacing the entire valve assembly. The V-9999-670 is designed for high-precision duty in hot water, chilled water, and glycol applications. By securing the actuator and preventing linkage slippage, it eliminates common performance issues like poor close-off or hunt-and-seek oscillations in VG7000 series bronze valves. This adapter is essential for maintaining the 90 lb force output required in modern hydronic balancing.

• Extends the service life of VT Series valve bodies by supporting field-upgradable actuator mounting hardware.
• Ensures accurate stem-up and stem-down calibration for VA-715X series synchronous motor actuators.
• Engineered with high-grade alloys to provide superior corrosion resistance and structural integrity in demanding HVACR environments.
• Reduces installation labor by providing a direct-fit solution for threaded stem valves, eliminating the need for custom linkages.

• Which actuators are compatible with the V-9999-670? This adapter is specifically engineered for Johnson Controls VA-715X series actuators, including incremental and proportional models.
• Can this be used on slotted stem valves? No, this kit is specifically for threaded stems; slotted stems require the Y20EBE-2 adapter kit.
• Does this work with VG7000 valves? Yes, the V-9999-670 is the standard interface for field-mounting 715X actuators to VT series bodies commonly found in VG7000 configurations.
