Bray Commercials ST-MTG-2/DS53 Valve Linkage

The Bray Commercial ST-MTG-2/DS53 Valve Linkage is a robust mounting kit designed to interface Bray direct-mount actuators with 1-inch to 3-inch butterfly valves. This industrial-grade linkage ensures precise torque transfer and alignment, critical for maintaining flow control accuracy in heavy-duty HVACR applications. Built with high-strength components to withstand high-cycle operations, the ST-MTG-2/DS53 features a ISO 5211 bolt pattern for standardized mounting, facilitating seamless field retrofits or new installations. Its rugged design eliminates mechanical play between the valve stem and the actuator drive, ensuring consistent valve modulation and long-term reliability in chilled water or steam systems. By utilizing this dedicated hardware, technicians can guarantee a secure mechanical connection that prevents premature wear on the valve packing and actuator gears, optimizing overall system performance in rigorous commercial environments.

• Precise Mechanical Coupling: Provides a rigid connection between the actuator and valve stem to ensure zero-backlash performance.
• Standardized Compatibility: Engineered specifically for Bray butterfly valves ranging from 1" to 3", ensuring a perfect fit without field modifications.
• Durable Construction: High-grade materials resist corrosion and mechanical fatigue in demanding mechanical room environments.
• Simplified Installation: Reducer bushings and mounting hardware are included to streamline the actuator field assembly process.

Common Technical Questions

What valve sizes is the ST-MTG-2/DS53 compatible with?
This linkage kit is specifically rated for Bray butterfly valves with nominal pipe sizes between 1 inch and 3 inches.

Does this kit include the mounting bracket and drive adapter?
Yes, the assembly includes the necessary mounting bracket and drive socket required to adapt the actuator to the valve stem.

Can I use this linkage with non-Bray actuators?
While designed for Bray series actuators, it may fit other actuators following the same ISO 5211 flange dimensions, though technical verification of the stem depth is required.
