Bray Commercial ST75-3-04/DM24-35 Valve
The Bray Commercial ST75-3-04 is a specialized 3/4 inch 3-way control valve engineered for precision water-side control in commercial HVAC systems. This assembly features a forged brass body with a chrome-plated brass ball and reinforced PTFE seats, ensuring reliable flow regulation in both mixing and diverting applications. Paired with the DM24-35 non-spring return actuator, this unit operates on a 24VAC/DC signal and provides a 35 lb-in torque output, suitable for high-differential pressure environments up to 50 PSI across the valve. The NSR actuator utilizes a brushless DC motor with microprocessor-controlled stall protection, extending the service life of the internal gear train. Technicians can rely on the field-reversible rotation and universal mounting orientation for streamlined installation in tight mechanical closets. Whether managing terminal units or air handlers, this Bray control valve provides the necessary flow coefficient (Cv) for accurate temperature modulation and system balancing.
Key Benefits for Contractors
- High-Torque Performance: The DM24-35 actuator delivers consistent 35 lb-in torque for smooth operation under high static pressure.
- Industrial Build Quality: Features a blowout-proof stem design and EPDM O-rings for superior chemical resistance in hydronic loops.
- Simplified Installation: Universal mounting bracket and standard 24V wiring minimize field labor and commissioning time.
- Enhanced Control Logic: Non-spring return operation ensures the valve maintains its last position during power interruptions, preventing sudden thermal shocks to the system.
Common Questions Regarding the ST75-3-04/DM24-35
What is the maximum fluid temperature rating for this assembly?
The ST75 series is typically rated for chilled water, hot water, and up to 50% glycol solutions, with a temperature range from 0°F to 250°F (-18°C to 121°C).
Can the DM24-35 actuator be used for proportional control?
The DM24-35 model is designed for floating/tri-state or on/off control; for 0-10VDC or 4-20mA modulating signals, a specific Bray "proportional" series actuator is required.
Is this valve suitable for steam applications?
This specific model is optimized for hydronic service. Steam applications require specialized high-temperature seals and different trim materials.
