Line pressure put on a detailed valve escalates the spring load on the upstream seat to effect a taut seal. An excellent range of FE qualified, high performance compact DBB cartridge valves for critical applications. The single units of these valves in many cases are used for applications in which complete certainty of shut-off is necessary.

Standard main gasket design is Lip-Seal type, secondary crisis seal constantly provided for fire-safe purpose. This might be reported to reduce the overall amount of the dual block valve construction. Instrument Double Block and bleed for stress connections Double Block and Bleed valves for pressure connections are usually used to separate instrumentation such as pressure indicators and lever gauges.

The upstream seal is leaking some, but this would not be a problem as the leakage is supposed to be overly enthusiastic by the bleeder—except once the bleeder is not working, either because one or both regarding the bleeder valves is closed, or because there is a clog in bleed line. 2 large balls that act as a block (both are closed), as well as the small ball act as the bleed (ball is in available place).
