Standards Addenda & Errata

It is also vital to take into account the specific application for the valve and ensure that the features required for isolation are fully tested during factory acceptance testing of the valve. For others, it adds substantial additional features and testing over and above the requirements of those standards e. Temperature class X is degrees F. Valve Basics Training to Expand in This isolation is critical in cases where leakage through a valve could have major consequences.

The choice of what type depends on the application and type of service.

While this 6e has several aspects that are positive, it is not really a design code like ASME BPVC section VIII, where material strength, corrosion allowance and formula for irregular shapes are taken into account.

Most codes covering piping in non-water service have tables that list valves covered by the code. Reach her at This email address is being protected from spambots. Reach him at This ediyion address is being protected from spambots.

API usually designates products by temperature class. A lot of changes were made in the 24th edition and they may have unintentionally screwed-up and caused confusion.

Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. Ron Manson is director of Applications Engineering, Cameron www. As stated, this procedure is inadequate to ensure the cavity pressure would not build beyond 1.

This smaller system or single valve unit serves to reduce the installation footprint, saves on extra piping requirements and reduces weight in critical areas.

Therefore, it does not really add anything to the edition list. If you are below F there is usually no consideration on temperature effects. Both DBB and DIB are used in applications for which critical isolation is needed to ensure that leakage does not occur.

Students Click Here Join Us! The purpose, in both editions, of cavity pressure relief is to ensure that when a valve is partially open and exposed to the full pressure rating, once closed, a feature such as self-relieving seats prevents overpressure beyond 1.

For example you have a 10, PSIG valve latet pressure can’t exceed 13, psig.

DBB and DIB: Which is which?

I’ll offer my opinion on the matter which mainly has to do with clarifying some of the wording of the 23th edition although it edituon to add more confusion. The mechanical wedge action of a double block-and-bleed plug valve compresses both sdition upstream and the downstream seals firmly against the valve body, which means no help is needed from the line pressure to affect a positive seal. For this reason, designs should be cross checked against a pressure vessel code.
