Bray Commercial ST05-2-03 Valve
For high-performance hydronic control, the Bray Commercial ST05-2-03 Valve delivers precision in a compact 1/2-inch frame. This 2-way characterized ball valve is engineered with a 2.6 Cv rating, utilizing a specialized Soft Touch internal insert that provides an equal percentage flow characteristic. This design ensures linear heat output and stable temperature control, effectively bridging the gap between the accuracy of globe valves and the cost-efficiency of ball valves. The forged brass body is paired with stainless steel ball and stem components, making it ideal for chilled water and hot water applications in high-demand commercial HVAC systems.
The ST05-2-03 features a blowout-proof stem and a universal mounting flange, facilitating seamless integration with various electric actuators. With a double O-ring stem seal and PTFE seats, this valve is built to handle close-off pressures up to 200 PSI while minimizing operating torque. This reduces the strain on the actuator and extends the life of the entire building automation system (BAS) assembly. When you need a reliable HVAC control valve for fan coils or VAV reheat applications, this 1/2" NPT model provides the high rangeability required for modern energy-efficient operations.
Key Benefits:- High Rangeability: Patented characterized insert provides precise throttling and eliminates hunting in the control loop.
- Durable Construction: Features a 2-piece forged brass body with a 300-series stainless steel ball for superior corrosion resistance.
- Low Operating Torque: Graphite-reinforced PTFE seats backed by EPDM O-rings allow for the use of smaller, more affordable actuators.
- Field Flexibility: The direct-mount bracket supports fast field installation and simplified maintenance for the technician.
- What is the maximum fluid temperature for this valve? This series typically supports water temperatures up to 284°F and low-pressure saturated steam up to 15 PSI.
- Can this valve be used for mixing or diverting? No, the ST05-2-03 is a 2-way model. For mixing or diverting applications, a 3-way ST series valve should be sourced.
- Which port should be the inlet? On models with a flow-characterizing disk, Port A must always be the inlet to ensure proper performance of the equal percentage curve.
