End connections
Define the interface.
Shown configuration: a double-flanged butterfly body, open disc, long shaft extension and hydraulic drive
| Connection detail | Connection / selection requirement |
|---|---|
| Connection options | Wafer / lug / RF flanged / butt weld (BW) |
| Mating interface | Confirm end standard, facing or weld preparation, pipe dimensions and installation envelope. |
The illustration shows one configuration. Published connection alternatives are options for enquiry; their availability depends on size, rating, material and design. Installation dimensions come from the drawing, not the illustration.
Materials
From body to seal.
| Component | Material / option |
|---|---|
| Body and bonnet | Cryogenic stainless steel; selected grade to confirm |
| Trim, seats and seals | Selected material schedule to confirm |
Published material alternatives are configuration-dependent. H.F. denotes hard facing; the exact grade and material certificates are confirmed with the offer.
Selection notes
Defined around your application.
- Triple-offset disc architecture
- Short body installation
- Hydraulic drive above the extension
| Engineering data | Configuration requirement |
|---|---|
| Hydraulic system | Specify working pressure, fluid, supply/return interfaces and the location of the power unit. |
| Motion and emergency duty | Confirm load, speed control, accumulator requirements, manual override and the required loss-of-pressure action. |
Series limits guide enquiry and are not verified availability or approved operating limits for every size, pressure and operator combination. Confirm the selected design and pressure-temperature rating.
The illustration does not include a hydraulic power unit. Accumulators, emergency energy storage and fail action are project selections.
Confirm sealing direction, seat construction, disc clearance and the selected flange or weld arrangement.
Published ratings do not establish suitability for every listed medium. Oxygen cleaning, material compatibility, trapped-liquid relief and project approvals are specified for the selected assembly. Liquid-hydrogen and helium service require a separate temperature and material review.
