Bray Commercials ST-MTG-1/DC44 Linkage Assembly

The Bray Commercials ST-MTG-1/DC44 Linkage Assembly is a precision-engineered mounting hardware solution designed to provide a secure mechanical interface between DC24-44-TP series actuators and ST05 valves. Built with high-strength steel to withstand the rigorous demands of industrial and commercial HVAC systems, this direct-mount linkage kit ensures optimal torque transfer and eliminates mechanical slop in floating control and non-spring return applications. Field technicians rely on the ST-MTG-1/DC44 for its ability to maintain precise stem alignment, which is critical for preventing premature packing wear and ensuring accurate valve positioning in automated damper and valve assemblies. Whether you are performing a retrofit installation or a new build, this assembly provides the structural integrity needed for 44 lb-in torque actuators operating in NEMA 2/IP54 environments. By utilizing this dedicated valve-to-actuator hardware, contractors can guarantee a stable, vibration-resistant connection that maximizes the service life of both the actuator and the valve body.

• Precision Stem Alignment: Engineered specifically for ST05 valves to reduce lateral stress on the valve stem and packing seals.
• High-Strength Construction: Manufactured from industrial-grade materials to ensure long-term durability in high-cycle actuator linkage applications.
• Seamless Compatibility: Optimized for the Bray DC-series, providing a perfect fit for 44 lb-in non-spring return actuators without field modifications.
• Reliable Torque Transfer: Robust mechanical engagement prevents slipping and maintains consistent control signals for automated HVAC operations.

Which actuators are compatible with the ST-MTG-1/DC44?
This linkage assembly is designed specifically for the Bray DC24-44 series, including the DC24-44-TP and DC24-44-TS models, ensuring a standardized mounting footprint.

Does this kit include mounting fasteners for the ST05 valve?
Yes, the ST-MTG-1/DC44 includes the necessary hardware to secure the linkage to the ST05 valve body and the actuator output shaft.

Can this linkage be used with spring-return actuators?
This specific kit is engineered for non-spring return DC-series actuators; for spring-return models, verify the mounting bridge and drive bush requirements against the manufacturer’s technical data.
