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.
