Bray Commercial 300800-11010119 Valve

The Bray Series 30 butterfly valve (300800-11010119) is a high-performance 8-inch wafer butterfly valve engineered for critical flow control in commercial HVAC and industrial process systems. This resilient seated butterfly valve features a cast iron body (ASTM A126 Class B) and stainless steel stem, providing the structural integrity required for dead-end service and high-velocity applications. The EPDM seat is designed for a bubble-tight shutoff, accommodating a broad temperature range for chilled water, hot water, and glycol-based systems. With its ISO 5211 mounting flange, this valve ensures seamless field-automation with electric or pneumatic actuators. The blow-out proof stem design and Nylon 11 coated disc enhance corrosion resistance and reduce torque requirements during operation.

Key Benefits:

• Corrosion Resistance: The Nylon 11 coated ductile iron disc and 416 stainless steel stem prevent pitting and ensure long-term seat integrity.
• High Flow Capacity: Streamlined disc profile minimizes pressure drop across the 8-inch wafer valve, optimizing pump efficiency.
• Reliable Sealing: Tongue-and-groove seat design isolates the cast iron body from the line media, eliminating the need for flange gaskets.
• Versatile Installation: The wafer-style body fits between ANSI 125/150 flanges, making it ideal for tight-clearance mechanical rooms.

Common Questions:

What is the pressure rating for the Bray 300800-11010119?
This Bray butterfly valve is typically rated for a maximum bidirectional pressure of 175 PSI, suitable for most commercial hydronic loops.

What media is compatible with the EPDM seat?
The EPDM liner is ideal for water, glycol, and dilute acids, but should not be used in systems containing petroleum-based oils or hydrocarbon solvents.

Can this valve be used for steam applications?
Standard Series 30 valves with EPDM seats are not rated for high-pressure steam; they are specifically designed for liquid-phase hydronic applications.
