Literature Available On Rockwell's New High Pressure/Temp. Valves

The Flow Control Division of Rockwell International Corporation, Pittsburgh, Pa., has introduced a new generation of highpressure high-temperature forged steel globe valves.

Incorporating modern technology and materials, the manufacturer reports the new Univalve® design offers higher pressure/ temperature ratings, a new two-piece yoke and bonnet assembly f o r easier in-line maintenance and a new graphitic stem sealing system that greatly reduces the need f or periodic stem packing adjustment or replacement.

Time-proven features are also retained in the new design. These include the inclined stem design f o r flow efficiency, a body guided disk f o r smooth throttling and shut-off and hardfacing of disk and seat f o r long service life.

Creation of the new design, available in seal-welded or unwelded models, followed extensive market surveys conducted by Rockwell which pointed out the need for a more efficient, faster, in-line valve maintenance and repair capability which could be performed by in-plant personnel.

The new model has a seal-welded bonnet f o r service on hazardous or toxic fluids where absolute protection f r om body-bonnet leakage outweighs the disadvantage of slower disassembly f o r maintenance. Where service doesn't require the seal-welded model, an unwelded bonnet model is available f o r faster in-line maintenance.

Three new service tools were developed to aid in efficient and fast maintenance of the new Univalves.

Both of the new Univalve models are available in classes 1690, 2680, and 4500.

Stop, stop-check and check Univalves in sizes Vz inch through 4 inches can be ordered with threaded, socket weld or butt welding end configurations.
