Bray’s Series 39 ceramic lined, slurry control valve is robustly designed to withstand the most demanding services including slurry, erosive, corrosive and scaling applications. Bray’s Series 39 valves are produced in easily serviceable, advanced wear resistant materials such as sintered silicon carbide ceramic or chrome-molybdenum iron. These durable valves deliver the highest quality and lowest total cost of ownership slurry control value solution on the market, leading to a more reliable and better performing product.
A. Adjustable packing: the stem packing is easily accessible without requiring removal of the actuator.
B. Direct mounting of actuation: one-piece high strength 17-4PH stainless steel used in all sizes. Bray’s double-D stem design and ISO 5211 top plate allow for direct mounting of Bray actuators, reducing package complexity.
C. Engineered stem bearings: the upper stem bearing made from a 316 stainless steel outer shell and TFE/glass liner along with the lower stem bearing made of PSZ ceramic provide excellent resistance to corrosion and distortion caused by mechanical loading and high temperatures.
D. Blow out proof stem: a retaining ring system is installed to ensure full retention of the stem in the unlikely event of internal stem failure.
E. Ceramic liner: the diamond ground liner, made from Silicon Carbide Ceramic, has a high hardness rating and in most applications the liner will outlast the hard-wearing single offset disc. This design is long lasting with minimal maintenance cost, as only a few parts will ever require servicing.
F. Designed control: the Series 39 is a control valve, the disc does not provide tight shutoff. The disc design maximizes flow with material options to minimize wear. This valve can in fact, swing through 360 degrees.
