Whether you’re managing a high-performance system or a demanding commercial installation, Bray’s Series 31H and Series 41 valves are engineered to deliver results that keep your projects on track and your systems running smoothly.
Why Bray Butterfly Valves?
Bray is a global leader in flow control solutions, known for precision engineering, durability, and innovation. With decades of experience and a reputation for quality, Bray Butterfly Valves are built to perform under pressure—literally and figuratively.
Series 31H – Contractor Grade Butterfly Valves
Series 31H lug-style resilient seated butterfly valve is drilled and tapped to meet ASME Class 125/150 and PN16 flanges. The durable, high strength one-piece stem design utilizes an efficient internal disc to stem connection.
Series 31H valves provide a primary and secondary seal between the disc and seat, as well as the stem and seat, ensuring the total encapsulation of line media with zero external leakage.
Key Benefits:
- One piece lug style. Polyester coating for excellent corrosion resistance. Nylon 11 coating is available as an option.
- Bray’s tongue and groove seat design provides complete isolation of flowing media from the body. The seat also features a molded o-ring which eliminates the use of flange gaskets.
- Casting is spherically machined and hand polished to provide a bubble tight shutoff, with minimum torque, and longer seat life. Bray’s resilient Nylon 11 coating comes as standard.
- Precision double “D” disc to stem connection drives the disc without the need for screws or pins. The close tolerance, double “D” connection that drives the valve disc is an exclusive feature of the Bray valve. Disassembly of the Bray stem is just a matter of pulling the stem out of the disc.
Applications:
HVAC, High Pressure, Dead End service and mor
Series 41 – High Performance Butterfly Valves
Series 41 is Bray’s standard McCannalok high-performance butterfly valve—engineered for high-pressure, high-temperature, and critical service applications. It’s the valve contractors rely on for durability, precision, and ease of automation.
