Ceramic Lined Butterfly Valve - Series 39
Features & Benefits
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.
