For high-pressure, high-temperature critical cyclic service, Newman's offers a complete line of forged "Safe-O-Seal" valves from 2 to 24 NPS in Class 600, 900, 1500 and 2500.
These valves feature the inherent advantages of forged bodies:
- Uniformity of structure
- Increased toughness
- Increased impact resistance
- Improved resistance to fatigue cracking
- Controlled grain flow
Combined and compatible with these features is the unique, patented "Safe-O-Seal" bonnet configuration. This design provided a seal welded barrier between the bonnet retention members and the flowing media. There are no sealing surfaces which could be damaged by corrosion, oxidation or in disassembly.
The simple, yet positive, sealing effect of this bonnet design is shown below. The effectiveness of this design in cyclic service and the relative simplicity of disassembly have been verified by independent steam testing to military specifications.
