Bray Commercial 301619-71500580 Sleeve Adaptor

The Bray Commercial 301619-71500580 is a high-precision B1 sleeve adaptor engineered to facilitate the mechanical connection between quarter-turn actuators and valve stems. As the direct replacement for Bray B1 components, this industrial-grade actuator sleeve insert ensures a standardized ISO 5211 interface, specifically designed to adapt a 16mm to 19mm square drive. For technicians performing field retrofits or automated valve assemblies, maintaining exact tolerances is critical to prevent hysteresis and premature neck wear. This butterfly valve adaptor is manufactured from high-strength materials to withstand the high torque outputs typically associated with Bray pneumatic and electric actuation systems. By utilizing this valve stem adaptor, contractors can achieve a secure, concentrically aligned fit that minimizes vibration and optimizes the transfer of force from the motor to the valve disc. Integrating the 301619-71500580 allows for seamless HVAC valve automation without the need for custom-machined bracketry or specialized couplers.

• Ensures a precise 16mm inner to 19mm outer square drive conversion for reliable torque transmission.
• Serves as the official replacement for B1 sleeve units, maintaining original equipment manufacturer (OEM) specifications.
• Compatible with a wide range of Bray butterfly valves and quarter-turn actuators using standard mounting patterns.
• Reduces installation downtime by providing a drop-in solution for stem diameter discrepancies.
• Constructed for high-cycle industrial applications, ensuring the integrity of the actuator-to-valve connection.

Is the 301619-71500580 compatible with non-Bray actuators?
Yes, provided the actuator follows ISO 5211 standards and requires a 19mm female drive to mate with a 16mm valve stem.

Can this sleeve be used for both pneumatic and electric actuators?
Correct. This sleeve adaptor is versatile enough for any drive type that utilizes square-cut stem geometry within the specified millimetric range.

Does this part require special lubrication during assembly?
While the part is designed for a dry fit, applying a thin layer of high-temperature grease can assist in seating the sleeve and preventing galvanic corrosion in high-moisture HVAC environments.
