API 6A Gate Valve, 3-1/16″, 15,000 psi

A 3-1/16″ (78 mm) gate valve to API 6A, rated 15,000 psi working pressure (15K). We supply it new from WOM, T3, NOV and Quality Oil Tools, and other API 6A manufacturers, to the PSL, PR, material class and temperature class you specify. The table lists the models and nameplate markings we have seen at this bore and rating, so you can quote a make and model directly.

Makes and models at this rating

Each row is what is marked on a valve we have photographed at this bore and pressure; a dash means the nameplate does not state it or is not legible. Your valve is built to the specification you put on the RFQ, not to these plates.

Rating, test and flanges

• Working pressure: 15,000 psi. API 6A shell test: 22,500 psi.
• Flanged ends: API 6BX flanges at this size and rating take a BX-154 ring gasket.
• Bore: full bore — the bore matches the nominal size, so wireline tools and pigs pass through.

Reading the nameplate

• PSL (product specification level, 1 to 4) sets the inspection, testing and traceability applied. PSL 3G adds a gas test.
• PR (performance requirement) is PR1 or PR2; PR2 valves have passed the design-validation testing in API 6A.
• Material class AA to CC is general service. DD, EE, FF and HH are sour service to NACE MR0175 / ISO 15156; a suffix such as -0.5 or -1.5 is the maximum H₂S partial pressure in psia, and NL means no limit.
• Temperature class letters combine: P = −20 °F to +180 °F; U = 0 °F to +250 °F; X = 0 °F to +350 °F. P+U covers −20 °F to +250 °F.
