AS-Schneider has expanded the comprehensive Double Block & Bleed product range of its proven VariAS-Blocks: These are now also available with a metal seated ball valve design. This means that the valves are suitable for use as a reliable primary isolation in industrial plants – at pressures up to 420 bar and under harsh operating conditions. The VariAS-Blocks by AS-Schneider are used in chemical plants and the oil and gas industry among other applications. The pressure must be continuously monitored and measured in the pipework used there. As primary isolation valves on the pressure tapping points, these special shut-off devices serve to reliably separate the impulse lines and process lines from each other. This not only allows reliable pressure measurements, but also protects people and the environment from dangerous and harmful process media.
