Bray Commercials ST05-2-01 Valve

The Bray Commercial ST05-2-01 is a high-performance 1/2 inch 2-way characterized ball valve engineered for precise fluid management in demanding HVAC hydronic systems. With a 1.3 Cv flow coefficient, this Soft Touch series valve integrates a patented Amodel flow characterizing insert to provide an equal percentage flow characteristic, ensuring stable temperature control in fan coils, VAV reheat coils, and baseboard applications. Designed with a forged brass body and rated for 360 PSI static pressure, the ST05-2-01 excels in both chilled and hot water service, including glycol concentrations up to 50%.

For technicians, the direct-mount valve design facilitates seamless integration with a variety of electric actuators, significantly reducing installation time and footprint in tight mechanical spaces. The blowout-proof stem and dual EPDM O-ring seals minimize operating torque and prevent leaks, even after long idle periods. This HVAC control valve is a reliable solution for building automation systems requiring consistent modulation and a tight ANSI Class IV close-off of up to 200 PSI. Its robust mechanical construction ensures longevity under standard operating temperatures up to 250°F, making it a staple for commercial contractors.

• Precise Flow Control: Patented characterized ball insert delivers equal percentage flow, matching globe valve performance with ball valve economy.
• Durable Construction: Features a forged brass body and nickel-plated brass ball for superior corrosion resistance in hydronic loops.
• Low Operating Torque: Advanced seat and seal design allows for the use of smaller, more cost-effective direct-mount actuators.
• System Versatility: ANSI Class IV leakage rating and high close-off pressure make it ideal for varied building automation requirements.
• Maintenance-Free Reliability: Self-centering stem and PTFE seats provide reliable operation without the need for periodic adjustments.

• What types of media is this valve compatible with? The ST05-2-01 is suitable for chilled water, hot water, and glycol solutions (up to 50%) within a temperature range of -22°F to 250°F.
• Does this valve require a specific mounting orientation? While it can be mounted in various positions, it is recommended to install it with the actuator above the horizontal plane of the pipe to prevent condensation from entering the motor.
• Can I field-mount an actuator to this valve? Yes, the universal mounting flange is designed for quick field-coupling with compatible non-spring return or spring return actuators.
