Features:
- Extended bonnets for Apollo® Top Entry Ball Valves are available for sizes 1/2" through 8" (15 through 200mm) in classes 150 and 300. Extended bonnets are standard for all class 600 valves.
- These bonnets provide excellent performance in high temperature or semi cryogenic applications.
- This bonnet design places the stem seals further away from the fluid flow thereby maintaining temperatures closer to ambient.
- Allows insulation to be applied to the bonnet decreasing a chance of disturbance as caused by operating a stem extension. If stem leakage occurs it can be immediately observed and corrective action taken.
- A valuable feature of the Extended Bonnet is that it can be retrofitted in the field at a later date. In addition to being able to order valves with several bonnet styles direct from the factory, kits are available that are pre-assembled with the stem, bonnet, packings, glands and jam nut installed and properly torqued for dependable performance. Contact the factory for kit part numbers for any specific valve or application.
Materials of Construction:
Extended bonnets are available in the same broad selection of materials of construction as those illustrated on page K5 for the bonnet, stem, stem packings, packing gland, nuts and body seals.
