Bray Commercial 310300-11010390 Valve

The Bray Commercial 310300-11010390 Valve is a 3-inch Series 31 lug style butterfly valve engineered for precision flow control in commercial HVAC and industrial process systems. This model is the direct technical replacement for 310300-11010119, now featuring a ductile iron body for enhanced structural integrity and pressure retention. Designed for dead-end service and frequent cycling, the 3" Bray S31 lug type valve utilizes high-performance seating materials to ensure bubble-tight shutoff. The lugged configuration allows for secure mounting between ANSI flanges and simplified downstream piping maintenance. As an industry-standard HVAC butterfly valve, it integrates seamlessly with pneumatic or electric actuators. Whether you are managing chilled water loops or hot water systems, this Bray butterfly valve 11010390 provides the high torque consistency and corrosion resistance required for rigorous mechanical room applications. Rely on this authentic replacement butterfly valve to maintain system hydraulic balance and operational efficiency.

• Ductile Iron Body: Upgraded from standard cast iron for superior durability and higher pressure tolerances in mechanical systems.
• Lug Style Design: Facilitates easy installation and allows for downstream piping removal without depressurizing the upstream side.
• Series 31 Performance: Field-proven architecture specifically optimized for high-cycle commercial HVAC applications.
• 3-Inch Nominal Pipe Size: Precise fit for 3" ANSI class 125/150 piping systems.
• Direct OEM Replacement: Replaces legacy part number 310300-11010119 with updated manufacture specs.

Is this valve compatible with existing 310300-11010119 setups?
Yes, the 310300-11010390 is the official direct replacement. While the body material has transitioned to ductile iron, the face-to-face dimensions and mounting flange patterns remain identical for drop-in compatibility.

Can this lug style valve be used for dead-end service?
Yes, the lugged body design is specifically engineered to handle dead-end service at full pressure ratings, provided it is installed with the appropriate flange bolting.

What media is this 3" Bray S31 valve suitable for?
It is primarily designed for water-based HVAC systems, including chilled water, condenser water, and hot water applications, ensuring consistent shutoff and throttling.
