B16.34 vs. API 6D

ANSI B.16.34

The Fisher V260 fully meets the design criteria established by ANSI-B16.34. Specifically, ANSI now has ruled on a 3-piece

ball valve and applicable wall section dimensions.

Most pipeline ball valves originated in design to API - 6D criteria which only addresses stresses and test pressures with no

specific wall thickness dimensional criteria. Some manufacturers appear to take a gray interpretation of ANSI B16.34 and

actually publish compliance to that standard in their Sales brochures.

- -. .

Informational requirements are available on demand. It is our contention that certain manufacturers do not comply if

audited to certify same. This issue should be of assistance in product differentiation of the new V260 ball valve.

This is a complex issue to raise with a customer but many Oil & Gas Companies (Distribution and Transmission) areevolving their design standards for control valves from API-6D to ANSI B16.34. Some manual and power on-off devices

are also under scrutiny.

In summary ANSI B16.34 requires more metal in the valve body than API-6D. Control valves are energy absorbers by

function as different from block valves. The additional metal in a control valve is generally a positive factor in systems

design philosophy.

series that o erate off downstream ressure

Compressor surge is minimum flow condit ion where the

compressor becomes unstable

Flow reversal occurs because there is not enough gas in the

impeller to impart momentum

Full flow reversals can dama e the com ressors bearin sbecause of thrust reversals
