Leak Prevention with Adjustable Stem Packing for Reliable Operation
Bray Series 51 brass, threaded ball valves are the ideal commercial utility valve for low-pressure applications. Series 51 threaded ball valves offer simple quarter-turn operation, low operating torque and a bubble-tight seal, making them an excellent choice for a wide range of general service applications, including: Water, Steam, Oil and Compressed gases.
Series 51 features a two-piece brass body design that simplifies maintenance and repair with a threaded closure manufactured with deep grooves, ensuring a tight seal. This feature enhances the reliability of the valve in various applications. The bottom entry blowout proof stem prevents stem ejection under line pressure.
