Twin-Blok II Large Bores 2 Inches and Above

Twin-Blok II Large Bores 2 Inches and Above

The AWARD WINNING (ASME Design award 2002)Twin-Blok II range of double block and bleed valves are designed to enable engineers to utilise a double barrier valve isolation instead of single isolate units.

Twin-Blok II saves money by eliminating the cost of pipework modifications due to it’s compact overall length which conforms to ANSI standard lengths of single ball valves. The TB type valve simply retrofits into the space left by a standard isolation ball valve that is to ANSI length.

* Three valves in the space of one ANSI length valve
* Single pressure joint from end-to-end
* Unique non-blocking annulus vent for extra safety

Twin-Blok II has the added advantage of having the unique non-blocking annulus venting facility and only one body joint from end to end - less joints means less potential leak paths. Users of this new innovative design of valve include SHELL, EXXON, TOTALFINA, CONOCO, KERR McGEE, QCPC, WOODSIDE, BP AMOCO and ANANDARKO.
