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.
A component material schedule is not published for this reference. Share your medium and service requirements so we can request the appropriate material specification.
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.
- Extended neck with drip plate
- Manual gear operator
- Bolted access cover
These size and pressure ranges are subject to technical confirmation. They are not verified availability or approved operating limits. Exact size, rating, materials and design temperature require written confirmation.
The size and pressure ranges are proposed enquiry targets for this valve type. A qualified configuration, design temperature, material schedule and certified outline drawing must be confirmed before quotation or selection.
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.
