Pressure Seal Gate Valve Design

Pressure Seal Gate Valve Design

Pressure Seal Gate Valve Design

(OP)
Dear all,
If I am not wrong,
Class 900 - 4" and Less
Class 1500 - 3" and Less
Class 2500 - 2" and less have FULL PORT whereas
Class 900 - 6” and larger
Class 1500 - 4” and larger
Class 2500 - 3” and larger have REDUCED PORT.
Could you advice where this detail specified. In ASME 16.34?
Thanks and best regards

RE: Pressure Seal Gate Valve Design

B16.34 does have a recommended port dia chart in non-mandatory appendix A. Pressure seal port diameters will vary vendor to vendor. Nothing really defines what "full port" means for most pressure seal valves. The B16.34 ports are not mandatory but many consider those as a full port guideline.

API 600, 602, and 623 all have required port diameters but those standards are usually applicable only to bolted bonnet valves.

Bottom line is you need to ask the supplier.

RE: Pressure Seal Gate Valve Design


In my opinion the answer is depending on wether you are a producer/constructor or an end user. This just to point out that technical answers not always are pure technical answers, but depending on background for the original question.

For a constructor you will have to decide and check on the giving (existing) specifications for constructional data. (Ref the answer from reverman above). This will limit you to what is allowed, but will not prohibit new developments, for instance larger ports than normally produced (if it is allowed).

For a manufacturor you will have to weigh the technical solutions acording to the market, eg. the applications and competition you are manufacturing to meet.

Both as a seller and buyer you will have to regard and weigh all available technical solutions, including other valvetypes for the application.
