Bray Commercials ST75-3-02 Valve

The Bray ST75-3-02 Soft Touch Series is a precision-engineered 3-way mixing and diverting valve designed for high-performance HVAC applications. This 3/4-inch NPT valve features a 2.0 Cv rating, providing accurate flow control for chilled water, hot water, and up to 50% glycol solutions. Constructed with a forged brass body and a chrome-plated brass ball, the ST75-3-02 ensures long-term reliability in demanding hydronic loops. The proprietary Soft Touch seat design reduces torque requirements, allowing for the use of smaller, more efficient Bray actuators. This characterised ball valve is optimized for linear flow response, preventing hunting in the control loop and ensuring stable discharge temperatures. For technicians, the universal mounting flange simplifies field installation and serviceability, making it a reliable standard for terminal unit control and small air handling systems.

Key Benefits:

• Precise Flow Control: 2.0 flow coefficient ensures accurate modulation for terminal units.
• Reduced Actuator Strain: Low-torque Soft Touch technology extends the service life of proportional control actuators.
• System Versatility: Suitable for both mixing and diverting configurations in hydronic systems.
• Durable Construction: Blow-out proof stem and reinforced PTFE seats handle high differential pressures.

Common Questions:

• What is the maximum fluid temperature for this valve? The ST75-3-02 is generally rated for fluid temperatures ranging from 35°F to 250°F.
• Can this be used with non-Bray actuators? While optimized for Bray linkages, it can be adapted to several standard HVAC valve actuators with the correct mounting kit.
• Is this valve suitable for steam applications? No, this model is specifically engineered for water and glycol-based hydronic systems.
