AS-Schneider, a global producer of custom valves, recently announced a new design specific for instrument piping. The company created its “Double Block & Bleed” series 20 years ago; since then, they have reported many improvements, and this new system is one of these innovations. The company based the design on the standard SHELL MESC SPE 77/165 and EEMUA 182.
The new development is a DBB ball valve for instrument piping. The main goal was to have a cost-effective solution. The result was the BA Series DBB ball valve, which has a very compact design. It’s lighter and takes up less space. It also boasts high-quality components for reliability and safety. AS-Schneider’s engineers mount these valves to the pipework. Thus, at least the first block valve coming from the process must have a robust process design. Process and instrument valves have different requirements, depending on function, medium, and pressure- volume-product.
