This is a Bray Series 21 lug-style butterfly valve with a 2-inch bore, commonly used in concrete batch plants for water metering and control applications. The valve features a durable ductile or cast iron body with a distinctive red Nylon 11 coating for corrosion resistance. Its tongue-and-groove seat design provides a bubble-tight seal and isolates the valve body from the process media, eliminating the need for separate flange gaskets. This valve is a critical component for controlling water flow in ready-mix and precast concrete production, requiring replacement due to wear or during system upgrades.
